Brecqhou (Brechou) is one of the Channel Islands, located just west of Sark. It is politically a part of Sark, which is in turn part of the Bailiwick of Guernsey.

Since 1993 the island has been owned by David and Frederick Barclay, who are better known as co-owners of the newspaper, The Scotsman. Since the purchase the Barclays have been in several legal disputes with the government of Sark, and have expressed a desire to make Brecqhou politically independent from Sark.

The Barclays have devised a flag for the island (identical to the Sark flag, with the exception that the Barclay arms are emblazoned on the bottom right), and have issued postage stamps annually since 1999.

A previous tenant of Brecqhou, Leonard Joseph Matchan, had issued stamps in 1969. Matchan occupied Brecqhou until his death on October 6, 1987.
