Robert McKissock Barnes Orr (26 January 1891 – 2 June 1948) was a Scottish footballer who played as a left back.
His longest spell at club level was 15 years with Third Lanark[2] (this was interrupted by World War I, although the Scottish Football League continued); the closest he came to winning a trophy in this time was reaching two finals of the Glasgow Merchants Charity Cup in 1910 (lost on a tally of corners following a draw)[3] and 1914 (a 6–0 defeat to Celtic),[4] and the final of the Glasgow Cup in 1923 (a loss to Rangers).[5]
Later in his career he also turned out for Morton, Dumbarton[6] and Clydebank, as well as for Crystal Palace in English football, for whom he made 70 league appearances, scoring twice.[1] [7] [8]
Orr was selected to play for Scotland in an unofficial Victory International in 1919,[9] played twice for the Scottish Football League XI[10] and toured North America in 1921[11] [12] [13] and South America in 1923[14] [15] with 'Scotland' (in reality, Third Lanark with a number of capable guest players).
