Northcliffe Media is to roll out a series of sport websites in Hull, Grimsby, Scunthorpe and Lincoln – all part of the publisher's North East region.
The Hull Daily Mail was this week the first to be launched, covering events in Hull and the East Riding of Yorkshire.
Sporthull.co.uk includes articles and video reports from the Mail's sporting journalists as well as user-generated content.
The site will focus on Hull's four main professional clubs: Hull City of the Football League Championship, rugby league rivals Hull FC and Hull Kingston Rovers, and ice hockey team Hull Stingrays.
There will also be a section covering semi-professional games and it will have an interactive area for fans, with a message board, blogs and pictures.
John Meehan, Hull Daily Mail editor and regional editorial director, Northcliffe North East, said: "Our sports staff are now providing content for sporthull.co.uk on a daily basis, as well as writing for the Mail's sports pages.
"They will be working as a fully integrated multimedia team, which reflects the approach we want to take in embracing digital publishing alongside our printed products."
In 2006 the Hull Daily Mail was joint winner of the Press Gazette Regional Press Awards innovation of the year for becoming the first regional paper to produce daily online video content, and was named Innovative Newspaper of the Year by the Newspaper Society in 2007.
Mail sports editor Stuart Rowson believes Northcliffe's sites covering the entire local sports spectrum mark a first for a regional newspaper.
He said: "Our aim is to give every sport the big-time treatment. Whether it is a local pub footie team, or Hull City, we're bringing it all together.
"The response from sports clubs and leagues has been fantastic so far – with some leagues and clubs abandoning their previous official sites in favour of using ours.
"Every day new clubs and new leagues want to come on board. It's big already, but it's going to be massive."
