Sir William Godolphin MP (1515–1570) was a 16th-century English soldier, knight, politician, and Member of Parliament (MP), whose career has been so confused with that of his father and namesake Sir William Godolphin that it is sometimes difficult to be sure which of the two held which offices.
The father was Member for Cornwall and High Sheriff during the reign of Henry VIII; the son worked closely with Thomas Cromwell as a young man, and with the help of Cromwell's support was elected MP for Cornwall in 1539.
He seems to have been drafted into the army command as an engineer, drawing on his knowledge of tin mining (which was the main source of his family's income in Cornwall).
Richard Carew in his Survey of Cornwall saying of him "He demeaned himself very valiantly beyond seas, as appeared by the scars he brought home, no less to the beautifying of his fame, than the disfiguring of his face".
After the capture of Boulogne, he was made its bailiff in recognition of the part he played in the victory, and also knighted.
