PZL.53 Jastrząb II (hawk) was a project of Polish pre-war fighter aircraft developed from PZL.50 Jastrząb and designed by Wsiewołod Jakimiuk of the PZL works. A single-seat low-wing monoplane was to serve as a multi-purpose fighter and escort and reinforcement for PZL.50 Jastrząb in the Polish Air Force.
