Ertuğrul or Ertuğrul Gazi (Ottoman Turkish: ارطغرل, romanized: Erṭoġrıl; Turkmen: Ärtogrul Gazy; died c. 1280/1281) was a 13th century bey, who was the father of Osman I. Little is known about Ertuğrul's life. According to Ottoman tradition, he was the son of Suleyman Shah, the leader of the Kayı tribe (a claim which has come under criticism from many historians)[b] of the Oghuz Turks, who fled from western Central Asia to Anatolia to escape the Mongol conquests, but he may instead have been the son of Gündüz Alp. According to this legend, after the death of his father, Ertuğrul and his followers entered the service of the Sultanate of Rum, for which he was rewarded with dominion over the town of Söğüt on the frontier with the Byzantine Empire. This set off the chain of events that would ultimately lead to the founding of the Ottoman Empire.

Nothing is known with certainty about Ertuğrul's life, other than that he was the father of Osman; historians are thus forced to rely upon stories written about him by the Ottomans more than a century later, which are of questionable accuracy. An undated coin, supposedly from the time of Osman, with the text "Minted by Osman son of Ertuğrul", suggests that Ertuğrul was a historical figure.: 31 Another coin reads "Osman bin Ertuğrul bin Gündüz Alp", though Ertuğrul is traditionally considered the son of Suleyman Shah.
In Enveri's Düsturname (1465) and Karamani Mehmet Pasha's chronicle (before 1481), Gündüz Alp is Ertugrul's father. After Aşıkpaşazade's chronicle Tevārīḫ-i Āl-i ʿOsmān (15th century), the Suleyman Shah version became the official one.
According to many Turkish sources, Ertuğrul had three brothers named; Sungur-tekin, Gündoğdu and Dündar. After the death of their father, Ertuğrul with his mother Hayme Hatun, Dündar and his followers from the Kayı Tribe migrated west into Anatolia and entered the Seljuk Sultanate of Rum, leaving his two brothers who took their clans towards the east. In this way, the Kayı Tribe was divided into two parts. According to these later traditions, Ertuğrul was chief of his Kayı Tribe.
As a result of his assistance to the Seljuks against the Byzantines, Ertuğrul was granted lands in Karaca Dağ, a mountainous area between Diyarbakır and Urfa, by Kayqubad I, the Seljuk Sultan of Rum. One account indicates that the Seljuk leader's rationale for granting Ertuğrul land was for Ertuğrul to repel any hostile incursion from the Byzantines or other adversary. Later, he received the village of Söğüt which he conquered together with the surrounding lands. That village, where he later died, became the Ottoman capital under his son, Osman I. Osman's mother has been referred to as Halime Hatun in later myths, and there is a grave outside the Ertuğrul Gâzi Tomb which bears the name, but it is disputed.
According to many sources, he had two other sons in addition to Osman I: Saru-Batu (Savci) Bey and Gündüz Bey. Like his son, Osman, and their descendants, Ertuğrul is often referred to as a Ghazi, a heroic champion fighter for the cause of Islam.
A tomb and mosque dedicated to Ertuğrul is said to have been built by Osman I at Söğüt, but due to several rebuildings nothing certain can be said about the origin of these structures. The current mausoleum was built by sultan Abdul Hamid II (1842 – 1918) in the late 19th century. The town of Söğüt celebrates an annual festival to the memory of the early Osmans.: 37 
In 1826, Ertuğrul Cavalry Regiment of the Ottoman Army was named in his honor. The Ottoman frigate Ertuğrul, launched in 1863, was named after him. Abdul Hamid II also had a yacht with the same name. The Ertuğrul Tekke Mosque (late 19th century) in Istanbul, Turkey and the Ertuğrul Gazi Mosque in Ashgabat, Turkmenistan (completed in 1998), are also named in his honor. The mosque in Turkmenistan was established by the Turkish government as a symbol of the link between Turkey and Turkmenistan.
Ertuğrul is one of several statues that surround the Independence Monument in Ashgabat, Turkmenistan. The statues depict people praised in the Ruhnama, a spiritual guide written by Turkmenistan president Saparmurat Niyazov. The Ertuğrul statue has also been depicted on a 2001 commemorative coin.
2 statues of Ertuğrul on horseback were placed by a private cooperative housing society in Lahore, Pakistan in 2020. They were inspired by Diriliş: Ertuğrul, a 2014 tv-series. A bust of Ertuğrul was erected in Ordu, Turkey in 2020, but was removed by local authorities after it was pointed out that it resembled the Ertuğrul-actor from the same tv-series.

That they hailed from the Kayı branch of the Oğuz confederacy seems to be a creative "rediscovery" in the genealogical concoction of the fifteenth century. It is missing not only in Ahmedi but also, and more importantly, in the Yahşi Fakih-Aşıkpaşazade narrative, which gives its own version of an elaborate genealogical family tree going back to Noah. If there was a particularly significant claim to Kayı lineage, it is hard to imagine that Yahşi Fakih would not have heard of it

In the tomb’s garden, there is a grave belonging to Ertuğrul’s wife, Halime Hâtûn. However, here there must be some information mistakes. The name of the esteemed woman who was the wife of Ertuğrul Gâzi and mother of Osman Gâzi is “Hayme Ana”, and her grave is in the Çarşamba village of Kütahya’s Domaniç district. Sultan Abdülhamid II, who had the Ertuğrul Gâzi Tomb repaired, also had the Hayme Ana Tomb as good as rebuilt in the same years. Therefore, the grave in Söğüt said to be of Halime Hâtûn, must belong to another deceased.
