Helena Ružicková (13 June 1936 in Prague – 4 January 2004 in Plzen) was a Czech actress.
Above all, Helena Ružicková was known for her comedic talents, and for films produced in the Czech Republic and East Germany.
She became popular especially thanks to her roles in Jaroslav Papoušek's comedy trilogy about the Homolka family (1969-1972), and in another comedy trilogy Slunce, seno...(1984-1991) directed by Zdenek Troška.
Her son, Jirí Ružicka, was also an actor until his death in 1999.
Ružicková herself died of stomach cancer on 4 January 2004 in a hospital in Pilsen.
However, director Zdenek Troška, her close friend, reported in a TV documentary about her life (2010) that her fight with cancer was successful and the real cause of death was kidney failure.
