Sir William Valentine Wood KBE (14 February 1883 – 26 August 1959) was a British businessman.
He worked for much of his life on the London, Midland and Scottish Railway (LMS), rising to become its President.
William Wood; Willie Wood to his railway colleagues and Val to his family, attended Methodist College, Belfast before joining the Northern Counties Committee (NCC) as an accountant.
During World War I he worked for the government, and when the Ministry of Transport was created in 1919 he became its first director of finance.
When Josiah Stamp was killed in 1941, Wood was asked to take over as President, a post which he held until the nationalisation of the Railways in 1948.
