The 1958 Open Championship was the 87th Open Championship, held from 2–5 July at the Royal Lytham & St Annes Golf Club in Lytham St Annes, England. Peter Thomson won his fourth Claret Jug in five years in a 36-hole Saturday playoff, four strokes ahead of Dave Thomas. It was the first playoff at the Open since 1949 and the seventh consecutive year that Thomson, 28, finished either as champion or runner-up. The 278 scored by Thomas and Thomson was a record low for the Open.
