Ali Çetinkaya, also known as "Kel" Ali Bey (1878 – 21 February 1949) was an Ottoman-born Turkish army officer and politician, who served eight terms in the Grand National Assembly of Turkey, including a period in 1939–40 as his country's first Minister of Transport.

He was born in Kara Hisâr-i Sâhib (present day Afyonkarahisar) in Hüdavendigâr Vilayet as the son of Ahmed Efendi.

When the Greek forces were landing at Smyrna on May 15, 1919, he was a lieutenant colonel and the commander of the Ottoman 172nd Infantry Regiment stationed in the Aegean coastal town of Ayvalık.

Ali played a key role in the first stage of the Greco-Turkish War of 1919–1922, starting with the opening battle against the occupying Greek forces.

His action is considered to mark the first shots fired by regular forces in the 1919–22 Greco-Turkish War which was part of the wider Turkish War of Independence, although there were earlier confrontations in which irregular militias participated, including the battle involving Hasan Tahsin in İzmir, as well as actions in Urla and Ödemiş.
