The Hertfordshire County Football Association Senior Challenge Cup, commonly called the Herts Senior Cup, is the oldest County-based football Cup competition based exclusively in Hertfordshire, England.

It was first contested in the 1886-87 season and won by Hoddesdon Town.

It is usually contested by the twenty-two most senior Clubs in the County, though this number has been higher and lower in previous years.

Since the 2004-05 season, finals have been staged at the Herts FA's headquarters at the County Ground, Letchworth Garden City, with the exception of 2010-11, when the final was moved to Underhill as the final was contested between two Football League clubs, Barnet and Stevenage, prompting safety concerns.

The current holders are St Albans City.
