Iosif Iser (21 May 1881 – 25 April 1958; born and died in Bucharest) was a Romanian painter and graphic artist. Born to a Jewish family, he was initially inspired by Expressionism, creating drawings with thick, unmodulated, lines and steep angles. After studies in Munich and Paris (with, among others, André Derain), Iser worked for the socialist press (Facla and the original version of Adevărul), publishing a large number of caricatures (most of them satirising the Romanian Monarchy). He also started his first series of paintings with Dobrujan themes, usually featuring local Tatar portraits.
