Osvald Polívka (May 24, 1859 – April 30, 1931), Austrian-born Czech architect associated with the Secession / Art Nouveau period in Prague. Polívka designed many of Prague's significant landmarks of the era, plus other work in Brno and elsewhere.
After graduating from Czech Polytechnic in Prague, his first important commission was a collaboration with Antonín Wiehl, the 1894 Prague City Savings Bank. Polívka's style evolved through his active years but he remained devoted to the collaborating with artists for aesthetic effect. For the ornate landmark Municipal House he coordinated the work of many significant Czech muralists and sculptors of the time, including his friend Alfons Mucha.
