Croatian Popular Party (Croatian: Hrvatska pučka stranka, [xř̩ʋaːtskaː pûːt͡ʃka strâŋka]) was founded in 1919, as political branch of the Croatian Catholic movement, and participated in elections in the Kingdom of Serbs, Croats and Slovenes until the royal dictatorship 1929.
In the 1920 elections, the party ran together with the Bunjevac-Šokac Party. The HPS had nine representatives elected: from the former Kingdom of Croatia-Slavonia were Velimir Deželić, Rev. Janko Šimrak and Stjepan Barić; from the former Kingdom of Dalmatia were dr. Ante Dulibić, dr. Dominik Mazzi and Mate Milanović-Litre; from Herzegovina were fra. Didak Buntić, dr. Marko Rebac and dr. Nikola Mandić.
After King Alexander declared a dictatorship on January 6, 1929 the party was abandoned and officially ceased to exist by police decree on January 21.
The modern-day Croatian Popular Party, founded in 1997, is named the same way.
