Wakefield Trinity Wildcats' home will continue to be named the Rapid Solicitors Stadium for the next two seasons.
It follows the club agreeing a new commercial deal with the company for the 2012 and 2013 seasons.
Wildcats commercial manager Martin Hopkins said: "This is a significant commercial deal for the club."
Rapid Solicitors started their origninal sponsorship at Belle Vue earlier this year.
"We have faith in the new owner, the club and their future plans," said Rapid Solicitors spokesman Martin Ward.
"Our commitment to the Wildcats is also a commitment to our involvement in communities."
