Beverly Joyce Fleitz (nee Baker; March 13, 1930 – April 29, 2014) was an American tennis player from the United States who was active in the late 1940s and during the 1950s.

Her six losses during this period were to Doris Hart (twice), Margaret Osborne duPont (twice), Maureen Connolly, and Magda Berescu Rurac.

She recorded wins over Louise Brough, Connolly, Berescu Rurac, Patricia Canning Todd, and Dorothy Bundy Cheney.

At the 1951 Wimbledon Championships, she defeated Althea Gibson in the third round 6–1, 6–3 and Margaret Osborne duPont in the quarterfinals before falling to Doris Hart in the semifinals 6–3, 6–1.

Fleitz was the top seed at the 1955 French International Championships, but she was upset by fourth-seeded Dorothy Head Knode in the semifinals 6–2, 6–3.

The veteran BBC tennis broadcaster Max Robertson observed "Louise was always prone to tighten up at important points, but [she] had a greater breadth of stroke and experience at her command, which just saw her through a keenly fought struggle.

That was the turning point, and Louise went on to win her fourth [Wimbledon] singles [title]...."[3] Afterward, Fleitz said "I've no excuses for my defeat.

Fleitz never played contemporaries Angela Mortimer, Ann Haydon, Christine Truman, Darlene Hard, Maureen Connolly, or Shirley Fry in a Grand Slam singles tournament.

Her win–loss record against other top players at those tournaments was as follows: Althea Gibson 2–1, Doris Hart 1–2, Louise Brough 0–3, Margaret Osborne duPont 2–1, and Maria Bueno 1–0.

At the Tri-State Championships in Cincinnati, Fleitz won the 1950 singles title and was the runner-up in 1949, with Berescu Rurac being her opponent in both finals.
