Eren Bülbül (1 January 2002 – 11 August 2017) was a Turkish 15-year-old boy from Maçka, Trabzon who was killed during the clashes between the Kurdistan Workers' Party (PKK) and the Turkish security forces in part of a Turkish military patrol during the Turkish-PKK conflict.

The son of Ayşe and Hasan Bülbül, Bülbül was one of 12 children. He spent his entire life in Maçka, Trabzon, as he went to local Çatak Primary School and later Maçka Anatolian Religious High School. He lost his father in 2016. He worked in his family's farm and liked sports, an ambitious fan of Trabzonspor.^[2]

On 11 August 2017, a group of PKK militants entered a house to obtain supplies after clashes with police. Bülbül saw them and informed the gendarmerie. He accompanied the police, showing them the house which the militants had entered. As a result of an attack by the PKK, both Bülbül and Gendarmerie Sergeant Major Ferhat Gedik were killed.^[3][4] After his death, 41 bullets were taken out from Gedik's body.^[5]

On 25 June 2019, Turkish Airlines launched a survey on Twitter to name the new Boeing 787 aircraft.^[10] Among the options suggested in the survey were ancient city names such as Perga, Assos, Göbekli Tepe, and Zeugma, but Eren Bülbül's name was not included in the list. When many Twitter users initiated a campaign to put the name Eren Bülbül on the plane, Turkish Airlines responded by naming the plane after Bülbül's hometown Maçka.^[11] In August 2021 Turkish manufacturer of special purpose and military vehicles, Katmerciler, presented a new tactical vehicle, Katmerciler Eren, named after Eren Bülbül.^[12][13]
