Andrew Dewar Gibb MBE QC (13 February 1888 – 24 January 1974) was a Scottish advocate, barrister, professor and politician.

Born in Paisley, the son of William Fletcher Gibb, a doctor, Gibb was educated at Paisley Grammar School, Homefield Preparatory School, Trinity College, Glenalmond, and the University of Glasgow, where he graduated with an MA in 1910 and an LLB in 1913.

[2] During World War I he served in France with the 6th Battalion of the Royal Scots Fusiliers, achieving the rank of major.

Gibb retired from his professorship in 1958, and was awarded an honorary Doctor of laws degree by the university the following year.

While he moved towards a Scottish nationalist position, he also retained a right-wing world view, and imperial questions remained prominent in his writings.
