Sir George Barclay Bruce (1 October 1821 - 25 August 1908) was a civil engineer.
Born in Newcastle upon Tyne he spent most of his professional life working on railway projects worldwide. In 1856 he was forced to return to the United Kingdom by ill health, and established a consultancy in Westminster.
He was elected president of the Institution of Civil Engineers in 1887, and for a second term in 1888 during which he was knighted. He served on the two royal commissions on the water supply of London in 1892 and 1897.
