Barış Atay Mengüllüoğlu (born 22 September 1981)[1] is a Turkish actor[2] and a politician of the Workers' Party of Turkey (TİP).

He acted in the theater play "Only a Dictator" (Turkish: Sadece Diktatör), which was widely viewed as a parody of Erdoğan.

[6] In November 2013, he was briefly detained due to suspected links to RedHack, a Turkish hacker group supportive of the Gezi Park protests, but released after a week.

[9] In 2018, he and Erkan Baş announced their resignation from the HDP and together joined the Workers' Party of Turkey (TİP), becoming their only representatives in the Parliament.

[11] After he demanded clarification in a case in which a sergeant was accused of the rape of the Kurdish 18 year old student İpek Er, but released from custody, he drew harsh criticism on him by the Turkish Minister of the Interior Süleyman Soylu, who blamed him of being a sympathizer of the Kurdistan Workers' Party (PKK) and the People's Liberation Party/Front (DHKP-C) and advised him "don't get caught".
