Jiří Šlitr (15 February 1924 in Zálesní Lhota near Jilemnice – 26 December 1969 in Prague) was a Czech songwriter, pianist, singer, actor and painter.

The double-act of Šlitr and Suchý made film appearances, firstly in Bylo nás deset (There Were Ten Of Us, 1963) and later in the successful musical comedy Kdyby 1000 klarinetů (If a Thousand Clarinets, 1964).

In 1965 Šlitr composed the jazz opera Dobře placená procházka (A Walk Worthwhile), which was staged in 2007 by the Czech-American director Miloš Forman at the National Theatre in Prague.

The duo parted company for a short time, and Šlitr put on a new play Ďábel z Vinohrad (The Devil from Vinohrady).

In 1967 he attended Expo 67 in Montreal, where he presented the show "Stars of Prague", and during his stay in America he exhibited drawings in Hollywood and Houston.

In 1968 he reunited with Suchý and after the events of the Prague Spring he restaged his earlier work The Devil from Vinohrady as a pointed response to the Soviet invasion of Czechoslovakia.
