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.

Initial design was prepared in 1939 and was based on PZL.50 Jastrząb but aircraft had greater bomb load (300 kg compared to 100 kg in PZL.50) and two additional 20 mm guns.
