Cezar Bolliac or Boliac, Boliak (23 March 1813 – 25 February 1881) was a Wallachian and Romanian radical political figure, amateur archaeologist, journalist and Romantic poet.

With fellow radicals Nicolae Bălcescu and Eftimie Murgu, Bolliac joined in Mitică Filipescu's conspiracy against Prince Alexandru II Ghica and, later in the year, entered the Freemasonry-inspired Frăția ("Brotherhood") secret society.

In Brașov, Transylvania (on Austrian domain), Bolliac began publishing Espatriatul, a paper which featured the subtitle Dreptate, Frăție ("Justice, Brotherhood"), a rendition of the revolutionary slogan.

He returned to Wallachia in 1858, after the Crimean War had led to a drastic decrease in Russian influence (allowing for radicals to regin their country), and took an archaeological study trip.

He later became a notorious antisemite, rejected the idea of naturalization for the Jews, and engaged in a polemic over this issue (and that of his version of Romanticism in general) with Junimea's Titu Maiorescu.
