What is the trophy awarded to the winner of The Open called?

The trophy awarded to the winner of The Open is called the Claret Jug. Its formal name is the Golf Champion Trophy.

The Claret Jug replaced the original Challenge Belt after Young Tom Morris won The Open three consecutive times from 1868 through 1870 and was allowed to keep the belt. A new trophy was commissioned by Prestwick Golf Club, the Royal and Ancient Golf Club of St Andrews and the Honourable Company of Edinburgh Golfers.

The Claret Jug was first associated with the 1872 Open, although it was not ready to be presented when Young Tom Morris won that year. Tom Kidd became the first champion to receive the actual trophy in 1873. The original is now kept at the Royal and Ancient Golf Club of St Andrews.

The champion holds the trophy for a year before returning it for the next Open. A replica is presented to the winner to keep permanently. The Claret Jug is easily confused with the Wanamaker Trophy, awarded at the PGA Championship, or the Green Jacket, awarded at the Masters.
