Brennan Peter Dickenson (born 26 February 1993) is an English professional footballer who plays as a midfielder for Scottish League One club Queen of the South.

Born in Ferndown,[2] former Southampton trainee Dickenson signed for Championship club Brighton & Hove Albion in January 2012 for an undisclosed fee from Dorchester Town.

[12] Still without a first-team appearance for Brighton, Dickenson was allowed to leave on loan for League Two once again, this time for Northampton Town until the end of the 2013–14 season on 8 February 2014.

[21] Bradley Garmston ousted Dickenson from the left-back position which he had become accustomed to playing for Gillingham by November 2015, with manager Justin Edinburgh saying that "choosing between them is probably the most difficult decision.

[28] He scored a brace in his next match on 16 August as he helped his side to a 3–2 win over Grimsby Town at the Colchester Community Stadium.

[32] Having firmly established himself as a regular starter as a left wing-back in the Colchester first-team, Dickenson said that "the spell I'm having at the moment is probably the best in my career.

[39] Dickenson turned down a new contract offer from Colchester, and on 30 May 2019 joined newly-promoted League One club Milton Keynes Dons on a free transfer effective from 1 July 2019.

[41] On 17 January 2020, following the mutual termination of his contract with MK Dons, Dickenson joined League Two club Exeter City on a short-term deal until the end of the season in response to Jack Sparkes sustaining a season-ending knee injury against Newport County on Boxing Day 2019 and other left sided players also being injured.

[46] On 3 August 2023, Dickinson joined National League club Oldham Athletic, signing a one-year contract.

[47] On 2 February 2024, Dickenson signed on loan with fellow National League side, Hartlepool United until the end of the 2023–24 season.

[48] In July 2024, following his release by Oldham Athletic, Dickenson signed a two-year contract with Queen of the South of Scottish League One.
