Ivo Brnčić or Brnčič (13 March 1912 – May 1943) was a Yugoslav author, essayist and literary critic of Croat origin, particularly notable for his assessment of interwar Slovene literature.
The first volume, which included his essays and critiques, was published in 1954 under the title A Generation in front of the Closed Doors (Slovene: Generacija pred zaprtimi vrati).
This expression, used in one of his earlier essays from the 1930s, became a popular and widespread designation of the generation of left wing Slovenian authors in the 1930s and early 1940s who embraced a lyrical version of neorealism (notably Ciril Kosmač, Miško Kranjec, Ludvik Mrzel, Karel Destovnik Kajuh and others).
Since the publication of his collected works in the 1950s, Brnčić has been frequently considered the foremost theorist of the social realist and neorealist literary movements in Slovenia in the 1930s.
Together with the left liberal Josip Vidmar and the Catholic France Vodnik, Brnčić was considered as the foremost Slovene literary critic of the 1930s.
