Robert Barr was a Scottish footballer who played as a right back, mainly for Third Lanark, making over 300 appearances for the Glasgow club in all competitions over 13 years.^[1][2]

Having joined the Warriors from a spell in the Army^[3][4] where he had risen to the rank of captain in the Black Watch,^[5] Barr won the Scottish Football League championship in 1903–04, playing in 24 of the 26 fixtures,^[6][7] and played in two consecutive Scottish Cup finals – a win over Rangers in 1905 via a replay^[8][9] and a loss to Heart of Midlothian in 1906.^[10]

In the first few years of his career between 1897 and 1901, he also won the Glasgow Merchants Charity Cup twice^[11][12] and was a beaten finalist on a further occasion,^[13] then claimed two winner's medals in the Glasgow Cup medals^[14][15][16] and was a runner-up twice^[17][18] in the space of five years between 1902 and 1907. A benefit match against Queen's Park was played in 1906.^[19]

Despite his success at club level, Barr's sole representative appearance was for the Glasgow FA in their annual challenge match against Sheffield in October 1906.^[2] He had stiff competition for international recognition in his position from the likes of Nicol Smith, Tom Jackson, Donald McLeod and Andrew McCombie.
