Theodore Ernest Els, born 17 October 1969, is a South African professional golfer.
A former World No. 1, he is known as "The Big Easy" due to his imposing physical stature (he stands 6 ft 3 in (1.91 m)) along with his fluid golf swing.
Among his more than 70 career victories are four major championships: the U.S. Open in 1994 at Oakmont and in 1997 at Congressional, and The Open Championship in 2002 at Muirfield and in 2012 at Royal Lytham & St Annes. He is one of six golfers to twice win both the U.S. Open and The Open Championship.
