The Newport and District Football League (currently billed as The Monmouthshire Building Society Newport and District Football League for sponsorship reasons) is a football league covering the city of Newport and surrounding areas in South Wales.

The headquarters are located at Newport Civic Centre.

The League's area consists of the city of Newport and the surrounding part of the historic county of Monmouthshire as far west as the county boundary at Bedwas, as far north-west as Abercarn and Wattsville, as far north-east as Sebastopol Bridge, and as far east as Llanwern, and Nash.

The Premier 'X' Division champions (or runners-up if the champions do not meet ground criteria) are promoted to the Gwent County League.

Clubs requesting places in the Premier Division will be interviewed by the Executive Committee.
