The Yorkshire ECB County Premier League was the top level of competition for recreational club cricket in Yorkshire, England, and between 1999 and 2015 was a designated ECB Premier League.
The competing teams in 2015, which was the league's last season, were: Appleby Frodingham, Barnsley, Castleford, Cleethorpes, Doncaster Town, Driffield Town, Harrogate, Hull, Rotherham Town, Sheffield Collegiate, Sheffield United, York, and Yorkshire CCC Academy. After the 2015 season, the league was reconfigured to form the basis of two new regionalised leagues.
Castleford, Driffield, Harrogate, Hull, York, and Yorkshire CCC Academy joined a new Yorkshire Premier League North, together with six clubs promoted from the York and District Senior League (Acomb CCC, Dunnington, Scarborough, Sheriff Hutton Bridge, Stamford Bridge, and Woodhouse Grange).
Appleby Frodingham, Barnsley, Cleethorpes, Doncaster Town, Rotherham Town, Sheffield Collegiate, and Sheffield & Phoenix United (formed from a merger between Sheffield United and their neighbouring club, Rotherham Phoenix) joined a new Yorkshire South Premier League, together with four clubs promoted from the South Yorkshire League (Aston Hall, Treeton, Whitley Hall, and Wickersley Old Village) and one from the Central Yorkshire League (Wakefield Thornes).
Both of these new leagues have ECB Premier League status, and the Bradford Cricket League plans also to obtain this status in 2017, as the Bradford Premier League, following its merger with the Central Yorkshire League in 2016. The winners of these three leagues, together with the winners of the North Yorkshire and South Durham Cricket League, will then contest a Yorkshire Championship.
