Jadwiga ("Jed") Jedrzejowska (born October 15 1912 in Kraków, Poland - died February 28 1980 in Katowice) was a tennis player from Poland. Because of her long and very difficult to pronounce name, she was called "Jed" or "Ja-Ja."

Jedrzejowska reached the singles final of a Grand Slam tournament on three occasions, still a record for Polish tennis.

• Wimbledon (1937): lost to Dorothy Round 6-2, 2-6, 7-5.
• US Championships (1937): lost to Anita Lizana 6-4, 6-2.
• French Championships (1939): lost to Simone Mathieu 6-3, 8-6.

In women's doubles, Jedrzejowska won the 1939 French Championships with Mathieu, defeating Alice Florian and Hella Kovac in the final 7-5, 7-5. Jedrzejowska's record in other Grand Slam women's doubles finals was as follows:

• French Championships (1936): Jedrzejowska and Susan Noel lost to Mathieu and Billie Yorke 2-6, 6-4, 6-4.
• US Championships (1938): Jedrzejowska and Mathieu lost to Alice Marble and Sarah Palfrey Cooke 6-8, 6-4, 6-3.

In the mixed doubles final at the 1947 French Championships, Jedrzejowska and Christian Caralulis lost to Eric Sturgess and Sheila Summers 6-0, 6-0.

At the age of 44, Jedrzejowska reached the women's doubles quarterfinals of the 1957 French Championships with partner Pilar Barril.
