Mike Blair (born April 20, 1981 in Edinburgh) plays professional rugby union at scrum half for Edinburgh Rugby and the Scotland national rugby union team. He is presently the understudy of Chris Cusiter in the Scottish team and together they maintain a friendly rivalry.

Mike came on in the second half of the Six Nations game against Wales at Murrayfield on March 13, 2005 after Chris Cusiter was injured, and played well enough to claim the starting berth in the Calcutta Cup game against England on March 19, 2005.
