The VFL Development League, officially known as the AFL Victoria Development League and formerly known as the VFL reserves, VFA seconds/reserves and VFA Second Eighteens, was an Australian rules football competition that operated as a second-tier competition to the Victorian Football League (VFL, originally known as the VFA) from 1928 until 2017.

Although formally operating as the VFA's reserves competition starting in 1928, the VJFA name was retained until the end of the 1932 season.

Coinciding with the seniors VFA competition, a second reserves division was established in 1961.

Several regional clubs were unable to sustain teams, with Bendigo and North Ballarat leaving the competition at the end of the 2009 and 2013 seasons respectively.

They were Box Hill, Casey, Coburg, Northern Blues, Port Melbourne, Sandringham, Werribee and Williamstown.
