Sir Oliver Ingham (about 1287–1344) was an English knight and landowner who served as a soldier and administrator under King Edward II of England and his successor, King Edward III. He was responsible for the civil government and military defence of the Duchy of Aquitaine during the War of Saint-Sardos and the early part of the Hundred Years' War.

Born about 1287, he was the son and heir of Sir John Ingham (1260-1309) of Ingham, Norfolk, who had served in the wars of King Edward I against the Scots, and his wife Margery. In 1310 he not only inherited his father's lands in Norfolk, Suffolk, Wiltshire and Hampshire but was himself summoned by King Edward II for military service against Scotland. Appointed a household knight of the king, he received many royal grants including the custody of Ellesmere Castle in Shropshire, keeper for the counties of Cheshire and Flintshire, and official positions in Shropshire and Wiltshire. As a knight banneret, he served in Scotland with the king in August 1322.
