Gary Speed (born September 8, 1969 in Mancot ) is a Welsh footballer, who plays in midfield. He currently plays for Bolton Wanderers F.C., after a £750,000 switch from Newcastle United F.C. in July 2004. He was also captain for the Welsh national team until recently, where he retired from international football after the side's 3-2 defeat to Poland in a World Cup qualifier.

Speed began his career with Leeds United F.C., winning the title with them in 1992. He moved to Everton F.C. in 1996, for a fee of £5,500,000. He then moved to Newcastle in 1998, and while there he became the club's most dependable midfielder. Newcastle's manager, Sir Bobby Robson, was sorry to see Speed leave the club, and acknowledged that he would do very well for Bolton.

He had been capped for Wales over 80 times, and holds the record for the most Premiership appearances. Besides being a strong tackler, Speed is noted for skill in set pieces, often scoring from them.

After his retirement from international football, he was recommended to take up the mantle of Wales' manager, by both the former manager Mark Hughes and fellow Welsh midfielder Robbie Savage. Bolton's manager Sam Allardyce has urged Speed to see out the rest of his 2 year contract with Bolton first. For his part, Speed has stated he will not apply for the position but would talk to the Welsh FA if approached.
