Muirfield is a privately owned golf links which 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 golf courses used in rotation for The Open Championship.

Muirfield has an unusual layout for a links course. Most links courses run along the coast and then back again leading to two sets of nine holes, the holes in each set facing roughly in the same direction. Muirfield, however, was among the first courses to depart from this arrangement and is arranged as two loops of nine holes, one clockwise, one anticlockwise. This means that assuming the wind direction remains the same throughout a round, virtually every hole on the course has a different apparent wind direction from the tee. No more than three consecutive holes follow the same direction at any stage. The course borders on Archerfield Wood, which features in "The Pavilion on the Links", the short story by Robert Louis Stevenson.

The Honourable Company of Edinburgh Golfers, now based at Muirfield, holds the claim of being the oldest verifiable organised golf club in the world, although the game of golf is several centuries older.
