Hildegard Krahwinkel Sperling (née Krahwinkel; 26 March 1908 – 7 March 1981) was a German-Danish tennis player. She won three consecutive singles titles at the French Championships from 1935 to 1937. Krahwinkel Sperling is generally regarded as the second-greatest female German tennis player in history, behind Steffi Graf. Sperling played a counterpunching game, predicated on speed, and wore down opponents. Helen Jacobs once wrote that Sperling was the third-best player she ever played, behind Helen Wills Moody and Suzanne Lenglen.
She became a dual-citizen after marrying a Dane, Svend Sperling, in December 1933.
