Frank Arthur Froehling III (May 19, 1942 – January 23, 2020) was an American tennis player.
During his college career at Trinity University Froehling recorded 46–5 in singles matches and won nine singles titles.
He was runner-up at U.S. National Tennis Championships in 1963 (where he beat Roy Emerson before losing to Rafael Osuna).
That year Froehling was ranked world No. 6 by Lance Tingay of The Daily Telegraph. Froehling was ranked in the top ten U.S. players on five occasions, reaching U.S. No. 2 in 1962 and No. 3 in 1963.
In 1966 Froehling won the Eastern Clay Court Championships defeating Herb Fitzgibbon in the final in a close five set match.
In 1971 Froehling reached the French Open semifinals (beating Arthur Ashe before losing to Ilie Năstase).
Froehling won a critical match for the U.S. in the 1971 Davis Cup final against Rumania, coming from two sets down to edge Ion Tiriac in a long fifth set. The U.S. won the Davis Cup final three matches to two. Froehling had won a demonstration match against Clark Graebner, who held a strong head-to-head advantage over Froehling, to qualify for the Davis Cup singles assignment.
