Filip "Fića" Kljaić (Serbian Cyrillic: Филип Фића Кљаић; 2 May 1913 – 5 July 1943) was a Yugoslav Partisan fighter during World War II and political commissar of the 1st Proletarian Brigade.

Kljaić was killed during the Battle of Zvornik and posthumously awarded the Order of the People's Hero on 25 September 1944.

Kljaić was born in the village of Tremušnjak,[1] in the Kingdom of Croatia-Slavonia of the Austro-Hungarian Empire, near the town of Petrinja, to a Croatian Serb family.

[2] In early July 1943, the 1st Proletarian Brigade, with Kljajić serving as their political commissar (since 21 December 1941[3]), attempted to liberate the occupied Bosnian town Zvornik from the Wehrmacht and the troops of the Axis puppet state, the Independent State of Croatia.

Following the ethnic cleansing of Liplje in 1992 at the start of the Bosnian War, the memorial suffered and became overgrown with shrubbery.
