The Mid-Herts Football League was a football competition based in England. It had two divisions including the Mid-Hertfordshire League Premier Division, which sat at level 13 of the English football league system. It was a feeder to the Hertfordshire Senior County League.
In the summer of 2006 the league merged with the North Hertfordshire League to form the new North & Mid-Herts Football League.
