William Henry Falconer (born 5 April 1966) is a Scottish former professional footballer and coach.
Falconer began his career playing for his home town club, Aberdeen, in 1982, and had an initial loan spell at Junior team Lewis United.
In 1991, Falconer transferred to Middlesbrough (then managed by Lennie Lawrence) in a swap deal involving Trevor Putney moving the other way.
After less than a season at Bramall Lane, in early 1994 Falconer was transferred back north of the border to Celtic for £350,000.
Although only at the club for two years, and behind others such as Pierre van Hooijdonk and Andreas Thom for a place in the side, he became something of a cult hero in Glasgow.
