Reginald Charles Allen (2 July 1858 in Glebe, New South Wales – 2 May 1952 in Sydney) was an Australian cricketer who played in one Test match against England in 1887.

Allen played for New South Wales and was top scorer in the first innings of the state match against the England team – under the name "A. Shaw's XI" – that immediately preceded the second Test.

His obituary in Wisden in 1953 says that he turned down the opportunity to tour England in 1888 under the captaincy of Percy McDonnell.

Although he was not athletic in build, he was also a successful all-round sportsman, representing Sydney University's First Grade Rugby Union team, and playing in the New South Wales Open Tennis Championship (which was then entirely amateur).

[2] He died in 1952 and his funeral proceeded from St Stephen's Church in Macquarie Street to the Northern Suburbs Crematorium.
