Kay Lund (21 January 1912 – 3 September 1979) was a German tennis player of the 1930s.
A native of Kiel, Lund was a two-time German junior champion who played Davis Cup doubles for Germany in 1935 and 1936. In the 1935 Inter-Zonal final against the United States, he and Gottfried von Cramm held five match points in their loss to Wilmer Allison and John Van Ryn, which would have given Germany a 2–1 lead in the tie.[1]
Lund was badly injured in World War II, losing an arm and leg.[2] No longer able to play tennis, Lund received assistance from his former doubles partner and long time friend von Cramm, who bought him a hotel in Baden Baden.[3]
