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.

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, 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).
