The Professional Development League is a system of youth football leagues that are managed, organised and controlled by the Premier League or by the Football League. It was introduced by the Football Association via the Elite Player Performance Plan in 2012.

The system was introduced in early 2012 and was active for the first time during the 2012–13 season. It is a successor to the Premier Reserve League, Premier Academy League and Football Combination. The Football League Youth Alliance makes up League 2 of the under-18 system. The system covers the under-18, under-21 and under-23 age groups.

Previously, clubs participating in the Premier Reserve League (the highest level of reserve football in England) were removed from the competition if their first team in the Premier League were relegated and replaced with a promoted team. Under the Professional Development League system, Premier League reserves teams' league status is not directly linked to the first team's Premier League status. Instead, there are three different Professional Development Leagues at each age-group level and clubs in the top four tiers of the English football league system are placed in the system based on the assessment of their academy for the Elite Player Performance Plan (EPPP).
