Clement Wing Hong Lam (Chinese: 林永康) is a Canadian mathematician, specializing in combinatorics. He is famous for the computer proof, with Larry Thiel and S. Swiercz, of the nonexistence of a finite projective plane of order 10.[1]

Lam earned his PhD in 1974 under Herbert Ryser at Caltech with thesis Rational G-Circulants Satisfying the Matrix Equation .[2] He is a professor at Concordia University in Montreal.

In 2006 he received the Euler medal. In 1992 he received the Lester Randolph Ford Award for the article The search for a finite projective plane of order 10.[3] The eponymous Lam's problem is equivalent to finding a finite projective plane of order 10 or finding 9 orthogonal Latin squares of order 10.[4]
