Harry Ralph Selley (9 December 1871- 24 February 1960) was a master builder and Conservative Party politician.
Born in Devon, he trained as a builder. He started his own construction business and built large numbers of houses in London.
In 1925 he was elected to the London County Council as a Municipal Reform councillor representing Battersea South. He held the county council seat until 1937.
Following two attempts at election to the House of Commons he became Conservative member of parliament for Battersea South at the 1931 General Election. He held the seat at the next general election in 1935. With elections cancelled due to the Second World War he remained MP until 1945 when he retired. He was knighted in the 1944 New Years' Honours for "political and public services".
In May 1945, aged 73, he won a bet with housing minister George Hicks by building a four-course wall of 200 bricks in the Commons Courtyard at the Houses of Parliament in less than an hour, whilst wearing a bowler hat.
