The South East Football Netball League (SEFNL) was an Australian rules football competition based in south-eastern Melbourne.
The league was established ahead of the 2015 season as a breakaway from the Casey–Cardinia division of the Mornington Peninsula Nepean Football League (MPNFL), but merged with the Yarra Valley Mountain District Football League (YVMDFL) at the end of 2018 to form the Outer East Football Netball League (OEFNL).
Berwick was the most successful club in the SEFNL's short history, winning three senior premierships and appearing in all four senior grand finals.
