Glenn David Tamplin (born 14 January 1972[citation needed]) is an English businessman, investor and former football club owner and manager.

[3] On 12 April 2023, the High Court of Justice Archived 7 July 2023 at the Wayback Machine declared Tamplin bankrupt.

[7] In November 2016, a Tamplin-led consortium had withdrawn their bid to take over Dagenham & Redbridge, after the board of directors removed their support for the offer.

[8] In December 2016, Tamplin purchased non-league football team Billericay Town;[9] the initial acquisition which was widely reported was followed by the signings of former star professionals Paul Konchesky, Jamie O'Hara and Jermaine Pennant.

[19] In November 2019, Tamplin joined Romford, immediately sacking manager Paul Martin and appointing himself in place.

[23] Later that month, however, one of the new employees stole from the club grounds, with Tamplin publishing CCTV footage of the incident on his Twitter account.

The court found Tamplin acted "negligently to a high degree" in committing the offences and the buried household and commercial waste could have interfered with nearby flood defences on the River Roding.

[26] In February 2018, Tamplin was under police investigation after alleged "gangster threats" were made by him to Billericay Town footballer Elliot Kebbie.
