Billy Gilliland (born 1957) is a former badminton player from Scotland who excelled from the mid-1970s through the mid-1980s. Although he won the Scottish national singles title in 1979, the tall, angular Gilliland was a doubles specialist at the international level with his greatest success coming in mixed doubles. Gilliland won mixed doubles at the prestigious All-England Championships with England's Nora Perry in 1985. He had previously reached the All-England final in both men's doubles and mixed doubles in 1982. He was a mixed doubles bronze medalist at the 1977 IBF World Championships with Joanna Flockhart. Though he won numerous tournaments abroad, perhaps Gilliland's most impressive badminton accomplishment was sharing twelve consecutive Scottish national mixed doubles titles equally with two partners, between 1976 and 1987. With regular partner Dan Travers, he won nine Scottish national men's doubles titles during that period, and men's doubles at the Commonwealth Games in 1986.
