The 2016–17 EFL Cup is the 57th season of the EFL Cup, formerly known as the Football League Cup, featuring all 92 clubs from the Premier League and the English Football League (EFL). It began on the week commencing 8 August 2016 and concludes with the final on 26 February 2017. The cup does not have a sponsor following the withdrawal of sponsorship from Capital One after four years as the Capital One Cup, but is renamed the EFL Cup after the Football League was rebranded as the EFL.
The winners will qualify for the 2017–18 UEFA Europa League third qualifying round. Manchester City are the defending champions.
