Piotr Firlej (died 1553) was a Polish nobleman (szlachcic).
In 1514 he participated in the Battle of Orsza and was a trusted adviser of Queen Bona Sforza and King Zygmunt II August.
[1] He was also the half-owner of a castle in Odrzykoń, sparking a dispute between him and Jan Skotnicki which would later inspire Aleksander Fredro's comedy Zemsta (The Vengeance).
[2][3] The dispute ended after thirty years with the marriage of one of Firlej's sons to Zofia Skotnicka.
