Alacahöyük or Alaca Höyük (sometimes also spelled as Alacahüyük, Aladja-Hoyuk, Euyuk, or Evuk) is the site of a Neolithic and Hittite settlement and is an important archaeological site. It is situated in Alaca, Çorum Province, Turkey, northeast of Boğazkale (formerly and more familiarly Boğazköy), where the ancient capital city Hattusa of the Hittite Empire was situated. Its Hittite name is unknown: connections with Arinna, Tawiniya, and Zippalanda have all been suggested.

The mound (Turkish höyük) at Alacahöyük was a scene of settlement in a continuous sequence of development from the Chalcolithic Age, when earliest copper tools appeared alongside the use of stone tools. During the Early Bronze Age, the mound was the center of a flourishing Hattian culture. It has been continuously occupied ever since, until today's modern settlement in the form of a small village. The standing and distinguishing remains at Alacahöyük, however, such as the "Sphinx Gate", date from the Hittite period that followed the Hatti, from the fourteenth century BC.
Thirteen shaft-grave "Royal Tombs" (EBII, ca. 2350-2150 BC) in Alacahöyük contained the dead in fetal position facing south. They were richly adorned with gold fibulae, diadems, and belt buckles and repoussé gold-leaf figures.
According to Trevor Bryce,
″There is a theory that the occupants of the tombs were not from the native Hattian population of central Anatolia, but were Kurgan immigrants from the region of Maikop in southern Russia, who spoke an Indo-European language and perhaps became rulers of the local Hattian population.″
Many of the artefacts discovered at Alacahöyük, including magnificent Hattian gold and bronze objects found in the Royal Tombs, are housed today in the Museum of Anatolian Civilizations in Ankara. Among these artefacts are gold and electrum standing cups and other vessels. The most unusual are the Alaca Höyük bronze standards; bulls or stags on pedestals whose purpose remains the subject of debate. The standards are cast in copper, many in the form of flat circles, half-circles or squares that are filled with an openwork network of cross bars, central crosses, and swastikas. Leonard Woolley found that the Royal Tombs "seem to belong to the end of a period, as marked by a stratum of destruction and the burning of the citadel. The culture which the tomb objects illustrate does not continue into the next historical phase, that of Kültepe". Modern assessment finds that the site continued as a flourishing community to the end of the Late Bronze Age. There was also a sizable occupation in Phrygian times.
A dam, dating from 1240 BC, was announced to be reopened for use on September 23, 2006. The dam was ordered by King Tudhaliya IV in the name of the goddess Hebat. According to ancient Hittite tablets, a drought struck Anatolia in 1200 BC, prompting the King to import wheat from Egypt so that his land would avoid famine. Following this, the king ordered numerous dams to be built in central Anatolia, all but one of them becoming non-functional over time. The one in Alacahöyük has survived because the water source is located inside the dam's reservoir.
In 1907, the Ottoman archaeologist Theodor Makridi Bey carried out brief explorations here for two weeks.  In the 1910s, German teams discovered royal tombs dating to the third millennium BC, as well as a Hittite town of the second millennium BC. The impressive sphinx gate surrounded by stone reliefs marked its entrance.  The town was heavily fortified with walls and towers due to the frequent raids of the Kaska people living in the mountainous region to the north. Excavations by the Turkish archaeologists Remzi Oğuz Arık and Hamit Koşay resumed in 1935 under the personal instructions of Atatürk who contributed from his own budget. The work, which continued until 1970, revealed considerable local wealth and achievement even before the time of the Hittites, with the earliest occupation dating from the 4th millennium BC. Tombs of the 3rd millennium BC feature metal vessels, jewelry, weapons, and pole finials of bulls, stags, as well as abstract forms often interpreted as solar symbols. Excavation at the site resumed in 1994, and is now directed by Dr. Aykut Çınaroğlu.
