John Houston, OBE, RSA, (1 April 1930 - 27 September 2008) was a Scottish painter and printmaker. He was born in Fife, Scotland, and studied at Edinburgh College of Arts, where he later taught between 1955 and 1989. He was married to the late Dame Elizabeth Blackadder, also a Scottish painter and printmaker.
Houston's work is characteristic of modern Scottish painting, direct in statement and rich in colour. Though he would include still-life and the human figure as subjects, it was the landscape that was always his truest subject. Houston produced a significant body of prints with Glasgow Print Studio throughout the eighties and nineties, mainly woodcuts, etchings and monotypes.
In 2011 an exhibition of paintings and prints by Elizabeth Blackadder and John Houston was held at Glasgow Print Studio in memory of Houston, and to mark the 80th birthday of Dame Elizabeth Blackadder.
