Brentford F.C. Reserves was the reserve team of Brentford. The reserve team played at varying times from 1900 until 2011. During the 2012 off-season, the English reserve football pyramid and youth system was overhauled under the Elite Player Performance Plan and replaced with a new Academy system and development leagues. Brentford's reserve team was relaunched as the Brentford Development Squad in 2011 and in 2012 it began competing in Professional Development League 2 South. After closing the academy in May 2016, the club withdrew from the Elite Player Performance Plan and Professional Development League and launched a new Brentford B team.
