The North East Club Winter League is a friendly tennis league for clubs from Northumberland, Durham and Cleveland that is played through the winter from October to March.

Matches are played on Sunday mornings and teams consist of 2 men and 2 women playing both straight and mixed doubles.

In 2023 the league merged with the Dunlop Northumberland and Durham & Cleveland Inter-Club Lawn Tennis League. The playing structure of the winter league will continue unchanged but the the governance of the league will now be under the constitution of the main N&D league.

The league was formed in 1899 for tennis clubs in Northumberland and Durham.

The Northumberland & Durham pop-up league is a temporary league for the summers of 2020 & 2021 to give willing players the chance to play some friendly but competitive tennis in the absence of the normal league season due to Corona virus.
