9TP (code for Polish: dziewięciotonowy polski - "9-tonne Polish") was a Polish light tank of early World War II era. A development of the earlier 7TP tank, it was to replace its predecessor in Polish service in 1940. Due to the outbreak of the war, only a limited number of early prototypes and development versions took part in battles of the Invasion of Poland.

The name of the tank was coined after World War II, technically the modified 7TP tanks were probably to retain the old designation regardless of the modifications. Alternative names include the "7TP wzmocniony", that is a "reinforced 7TP".
