Muirfield Golf Course is a privately owned links course and is the home of The Honourable Company of Edinburgh Golfers. Located in Gullane, East Lothian, Scotland, overlooking the Firth of Forth, Muirfield is one of the courses used in rotation for The Open Championship which the club has hosted sixteen times, most recently in 2013 when Phil Mickelson lifted the trophy.

Unlike most links courses that run along the coast and then back again the Old Tom Morris design at Muirfield was among the first to be arranged as two 9-hole loops, one clockwise, one anticlockwise. The course was altered and improved by Harry Colt and Tom Simpson in 1928, however, they kept Morris's original layout where every hole on the course has a different apparent wind direction from the tee and no more than three consecutive holes follow the same direction at any stage.

In 2010 and 2011, changes were made at fifteen holes following a review by Martin Hawtree to ensure that Muirfield remained a suitable challenge. New bunkers in selected drive areas were added, greenside bunkers were repositioned, the greens were extended to provide more championship pin positions and the course was lengthened to 7,245-yards whilst retaining its par of 71.

The Elizabethan clubhouse is delightfully traditional and full of character and provides members and visitors with both bar and restaurant services. Golfers will find a Pro shop with caddies available for hire as well as a full driving range, chipping area, and putting green.
