Michael Paul O'Callaghan (1936 — 15 April 2018) was an Irish international rugby union player.
Cork-native O'Callaghan was a prop who lacked the height traditionally required for the position, but was quick around the pitch.
He played his club rugby for Sundays Well, London Irish and Young Munster.
[1] O'Callaghan was capped three times for Ireland, debuting in a draw against Wales at Lansdowne Road during the 1962 Five Nations.
[1] A Munster representative, O'Callaghan was one of their best performers in a narrow loss to the touring All Blacks in 1963, playing the majority of the match with his head stitched and covered in bandages.
