Roger Michael Needham (February 9, 1935February 28, 2003) was a British computer scientist.

Needham began his undergraduate studies at the University of Cambridge in 1953, graduating with a B.A. in 1956. His Ph.D. thesis was on applications of digital computers to problems of classification. He became a highly respected scholar and worked on a variety of key computing projects in security, operating systems, computer architecture (capability systems) and local area networks.

Among his theoretical contributions is the development of the Burrows-Abadi-Needham logic for authentication, generally known as the BAN logic. His Needham-Schroeder (coinvented by Michael Schroeder) security protocol forms the basis of the Kerberos authentication and key exchange system. He also codesigned the TEA and XTEA encryption algorithms.

He joined Cambridge's Computer Laboratory, then called the Mathematical Laboratory, in 1962, became head of the lab in 1980 and remained there until his retirement in 1995. Needham set up Microsoft's UK-based Research Labs in 1997.

In 2001 he received a CBE for his contribution to computing. He was married to Karen Spärck Jones.

He died of cancer in February 2003 at his home in Coton, England.
