WALLIS Teagan will be Millwall's new main shirt sponsor for next season.
The building and maintenance company sponsored the Lions’ development squad kit during the 2014-15 campaign, and will now be on the front of the club's new home and away shirts next season.
The south London company had been secondary shirt sponsors for the last two seasons.
And Millwall confirmed that they have cancelled the previous agreement with Euroferries Express.
Peter Trotter, joint managing director of Wallis Teagan, told Millwall's official site: "We are pleased that our partnership with Millwall is continuing into the 2015-16 season for what is the start of an exciting new era for the club.
"Millwall's strong community values are something we at Wallis Teagan like to identify with in terms of our own business operations and this latest partnership agreement is an exciting opportunity for our relationship with the football club to develop even further."
Millwall chief executive Andy Ambler added: "We have formed a close bond with Wallis Teagan in recent years, particularly over the last two seasons.
"Wallis Teagan have refurbished the club shop, home dressing room, plus a number of executive boxes, and we are excited that such a successful local company are becoming the club's principal partners for the 2015-16 campaign."
