Joseph Nicol Walker (born 29 September 1962) is a Scottish former professional footballer, who played as a goalkeeper for several clubs in Scotland and England.
Walker did play in the 1987 Scottish League Cup Final against Aberdeen, which Rangers won after a penalty shoot-out, while injuries to Woods the following season also meant Walker deputised in twelve games to earn a Scottish League title medal.
His time at Tynecastle developed into a see-saw battle with Henry Smith for the starting goalkeeping role, both men earning international recognition when in the Hearts first team but enduring significant spells on the sidelines.
Smith eventually won the duel and, after a loan spell with Burnley, Walker moved to Partick Thistle in 1994 in a part-exchange deal for Craig Nelson.
He left Pittodrie in 1999 after he was supplanted by Derek Stillie, winding down his career with short spells at Ross County and Inverness Caledonian Thistle.
