Hubert Charles Day (8 May 1908^[5] – 27 June 1977) was a rugby hooker who played rugby union for Newport and rugby league for Salford.^[2] He was awarded five caps for Wales under union rules and was part of the Welsh side that won the 1931 Five Nations Championship.^[3][4] At Salford Day forged a reputation as the greatest hooker to play for the club, his record 488 appearances for the club went unbroken for over 35 years.

Bert Day was born in Griffithstown, Monmouthshire, and he died aged 69 in Salford, Greater Manchester, England.

Day was first selected for Wales in the 1930 Five Nations Championship in a match against Scotland at Murrayfield. Day was one of two new caps in the Welsh squad alongside Swansea's Dai Thomas. Wales lost the match 9-12, but Day was reselected for the next game of the tournament in a win over Ireland, under the captaincy of Jack Bassett. The final game of the Championship was an away game to France. The match was notoriously bad tempered with the referee forced to make multiple stoppages to reproach both packs as fist fights broke out throughout the game. Day himself was kicked in the mouth and was forced to leave the pitch to have several stitches in his lip.

Day played twice in the 1931 Five Nations Championship which Wales won after drawing against England and beating the remaining three teams. Day's final match was the second game in a victory over Scotland at the Cardiff Arms Park. Day later switched codes, 'Going North' to join Salford RLFC.
