All attempts occurred in the German Reich, except where noted. All attempts involved citizens of the German Reich, except where noted. No fewer than 42 plots have been uncovered by historians. However, the true number cannot be accurately determined due to an unknown number of undocumented cases.
|1932||Hotel Kaiserhof (Berlin)||Unknown||Hitler and several members of his staff fell ill after dining at the revered Kaiserhof hotel in Berlin. Poisoning was suspected, but no arrests were made. Hitler himself seemed least affected by the alleged poisoning, possibly due to his vegetarian diet.|

|1934 - 1939||Charlottenburger Chaussee, Berlin||Noel Mason-Macfarlane||Lieutenant-Colonel Noel Mason-Macfarlane, Military Attache to the British Embassy in Berlin, did not trust Hitler and tinkered with the notion that it might pay off to contrive Hitler's assassination. It could have been achieved by sniper rifle-shot from Mason-Macfarlane's drawing room which overlooked the Charlottenburger Chaussee where there was a saluting base podium from which Hitler received the salute from the German armed forces during his birthday parade on 20th April. When Mason-Macfarlane proposed this plan to his superiors, it was turned down. The British Foreign Secretary, Lord Halifax argued that "We have not reached that stage ... when we have to use assassination as a substitute for diplomacy".|
|1935||Berlin||Marwitz group||Several officials in the German Foreign Office attempted to instigate an army coup against Hitler; they distributed a letter asserting that "The oath of allegiance to Hitler has lost its meaning since he is ready to sacrifice Germany", and that "now was the time to act."|

|September 28, 1938||Berlin||Hans Oster, Helmuth Groscurth||Generalmajor Hans Oster and other high-ranking conservatives in the Wehrmacht formed a plan to overthrow Hitler if he declared war on Czechoslovakia. Forces controlled by the plotters would storm the Reich Chancellery, arrest or assassinate Hitler, take control of the government, and restore the exiled Wilhelm II as Emperor. The plan was abandoned after Britain and France agreed to German annexation of Sudetenland in the Munich Agreement, neutralizing the immediate risk of war. Many of the conspirators later took part in the 1944 20 July Plot.|
|November 9, 1938||Munich||Maurice Bavaud||Swiss theology student Maurice Bavaud posed as a reporter and planned to shoot Hitler from the reviewing stand as he passed through the parade. His view of Hitler was blocked by the unwitting crowd and he was forced to abandon the plan. He then attempted to follow Hitler but failed. On his way back to Paris he was discovered by a train conductor and turned over to the Gestapo. Bavaud was executed by guillotine at Berlin's Plötzensee Prison on the morning of 14 May 1941.|
|October 5, 1939||Warsaw||Michał Karaszewicz-Tokarzewski, Service for Poland's Victory||General Michał Karaszewicz-Tokarzewski and other members of the Polish Army attempted to detonate hidden explosives during Hitler's victory parade in Warsaw. 500 kg of TNT were concealed in a ditch, ready to be detonated by Polish sappers. However, at the last moment, the parade was diverted and the saboteurs missed their target.|
|November 8, 1939||Munich||Johann Georg Elser||German carpenter Georg Elser placed a time-bomb at the Bürgerbräukeller in Munich, where Hitler was due to give his annual speech in commemoration of the Beer Hall Putsch. Hitler left earlier than expected and the bomb detonated, killing eight and injuring sixty-two others. Following the attempt, Elser was held as a prisoner for over five years until he was executed at the Dachau concentration camp less than a month before the surrender of Nazi Germany.|
|1939||Berlin||Erich Kordt||German diplomat and resistance fighter Erich Kordt hatched an assassination plot along with officer Hasso von Etzdorf to plant explosives, but the plan was abandoned after the security restrictions following Georg Elser's attempt to kill Hitler made the acquisition and concealment of the necessary explosives too dangerous.|
|1941–1943 (several)||Berlin||Beppo Römer||Beppo Römer, along with several co-conspirators of the resistance group Solf Circle, plotted once again to assassinate Hitler. He obtained funds from co-conspirator Nikolaus von Halem and kept track of the Hitler's movements through a contact at the Berlin City Commandment. However, before an opportunity presented itself, the plot was unraveled by the Gestapo. Römer was sentenced to death on 16 June 1944 and executed on 25 September of that year at Brandenburg-Görden Prison in Brandenburg an der Havel.|
|1943||Walki, Ukraine||Hubert Lanz, Hans Speidel, Hyazinth Graf Strachwitz||General der Gebirgstruppe Hubert Lanz and Generals Hans Speidel, Hyacinth Graf Strachwitz, and Paul Loehning planned to arrest or kill Hitler during his visit to Army Detachment Kempf in Ukraine. Strachwitz was to surround Hitler and his escorts with his tanks. Lanz stated that he would have then arrested Hitler, and in the event of resistance, Strachwitz's tanks would have killed the entire group. Hitler cancelled the visit and the plan was dropped. Lanz told of this plot after the war. However Strachwitz's cousin, Rudolf Christoph Freiherr von Gersdorff, who attempted to assassinate Hitler in 1943, said Strachwitz had expressed the belief to him several times that killing Hitler would have constituted murder. That is, Strachwitz was too much a Prussian officer to consider assassinating Hitler, which suggests that the plot never existed.|
|March 13, 1943||Flight to Smolensk||Henning von Tresckow, Fabian von Schlabrendorff||On the return flight from a front visit, Hitler visited the headquarters of the Army Group Center in Smolensk. During the visit there were several attempts on his life:
|March 21, 1943||Berlin||Rudolf Christoph Freiherr von Gersdorff||After becoming close friends with leading Army Group Center conspirator Colonel (later Major-General) Henning von Tresckow, Generalmajor Gersdorff agreed to join the conspiracy to kill Hitler in order to save Germany. After Tresckow's elaborate plan to assassinate Hitler on 13 March 1943 failed, Gersdorff declared himself ready to participate in an assassination attempt that would entail his own death.
On 21 March 1943, Hitler visited the Zeughaus Berlin, the old armory on Unter den Linden, to inspect captured Soviet weapons. A group of top Nazi and leading military officials – among them Hermann Göring, Heinrich Himmler, Field Marshal Wilhelm Keitel, and Grand Admiral Karl Dönitz – were present as well. As an expert, Gersdorff was to guide Hitler on a tour of the exhibition. Moments after Hitler entered the museum, Gersdorff set off two ten-minute delayed fuses on explosive devices hidden in his coat pockets. His plan was to throw himself around Hitler in a death embrace. A detailed plan for a coup d'état had been worked out and was ready to go but, contrary to expectations, Hitler raced through the museum in less than ten minutes. After Hitler had left the building, Gersdorff was able to defuse the devices in a public bathroom “at the last second.” After the attempt, he was transferred back to the Eastern Front, where he managed to evade suspicion.
|November 16, 1943||Wolf's Lair||Axel Freiherr von dem Bussche-Streithorst||Encouraged by Claus Stauffenberg, Major Axel von dem Bussche agreed to carry out a suicide bombing in order to kill Hitler. Bussche, who was over two meters tall, blonde and blue-eyed, exemplified the Nazi "Nordic ideal" and was thus chosen to personally model the Army's new winter uniform in front of Hitler. In his backpack, Bussche concealed a landmine, which he planned to detonate while embracing Hitler. However, the viewing was canceled after the rail car containing the new uniforms was destroyed in an Allied air raid on Berlin.|
|January 1944||Wolf's Lair||Ewald-Heinrich von Kleist-Schmenzin||Ewald von Kleist attempted a scheme similar to Von dem Bussche's. However, the uniform inspection was once again postponed, and eventually cancelled by Hitler.|
|March 11, 1944||Berghof||Eberhard von Breitenbuch||On 9 March 1944, covert German resistance member Busch and his aides were summoned to brief Hitler at the Berghof in Bavaria on 11 March. In discussion with Tresckow, Breitenbuch declined to make a suicide bomb attempt attack. Instead he would try to shoot Hitler in the head with a 7.65mm Browning pistol concealed in his trouser pocket. Busch and Breitenbuch travelled on a Condor aircraft to Bavaria, and were allowed into the Berghof. But SS guards had been ordered – earlier that day – not to permit aides into the conference room with Hitler, preventing Breitenbuch's attempt.|
|July 20, 1944||Wolf's Lair||Claus von Stauffenberg|
