Samochód pancerny wz. 28 (literally "Armoured car, year 1928 model") was a Polish armored car of the 1920s.
Based on the French-built Citroën-Kegresse B2 10CV half-track chassis, the vehicle became the standard armored car of the Polish Army. However, due to low speed and problems with reliability in 1933 the vehicles were returned to the factory and rebuild as all-wheel Samochód pancerny wz. 34.
The cars came in one of two basic variants: one armed with a 37 mm Puteaux SA 18 gun, the other with one Ckm wz. 25 Hotchkiss machine gun. By 1939 all but a handful (3 or 4) were converted to wz. 34 armored cars, the remainder remained in training centers.
