Jadwiga ("Jed") Jedrzejowska [jad'viga j?nd??'j?fska] (15 October 1912 – 28 February 1980) was a Polish tennis player who had her main achievements during the second half of the 1930s.
Because her name was difficult to pronounce for many people who did not speak Polish, she was often called by the nicknames "Jed" or "Ja-Ja".
