Claire Joan Schillace (March 29, 1921 – January 17, 1999) was a center fielder who played from 1943 through 1946 in the All-American Girls Professional Baseball League.

After receiving a tryout invitation, she became one of the first four players signed by the league for its inaugural season, joining Ann Harnett, Shirley Jameson and Edythe Perlick.

[4] Claire served as a consultant for A League of Their Own, the 1992 film about the AAGPBL starring Geena Davis and Madonna, both of whom were novices to the sport.

At one point, director Penny Marshall told Claire to teach Madonna "everything you know about baseball in a half an hour".
