Penrith are mourning the loss of one of the most talented players to have worn a Panthers jersey, Kevin Dann.

The former NSW fullback, who played 121 games for the club from 1977-84, has died at the age of 62.

Penrith posted a tribute to Dann on social media on Sunday night to say "with heavy hearts we acknowledge the passing of Kevin Dann - Panther No.138. Our sincere thoughts are with his family and friends".

A Blacktown junior, he made his debut as a teenager and retired at the age of 25 at the end of 1983 before playing one more match the following season during a brief comeback.

He represented NSW in a non-Origin match against Queensland in 1980, becoming the first Panther to gain state selection, but further higher honours eluded him, stuck behind several fine fullbacks in that era such as Graham Eadie, Greg Brentnall and Garry Jack.

Dann racked up 322 points from 40 tries and 100 goals for the Panthers.

Former teammate Darryl Brohman described Dann's death as a terrible loss posting a tribute on social media: "Terrible news today with the passing of Kevin Dann. Stan was a tremendous bloke and a wonderful footballer. A very classy fullback who had the chance to be the Panthers first ever Australian representative. RIP Stan."
