Danske Bank has extended its sponsorship of the Irish Premiership and Women's Premiership for a further three years.
The partnership with the Northern Ireland Football League is now in its eighth year.
"We're so looking forward to the next three years working together," said NIFL managing director Andrew Johnston.
"We have worked in partnership with Danske Bank since the inception of the NI Football League.
"Over that time we have built and developed a fantastic relationship which has not only brought more attention to the local game, but has seen attendance figures increase year on year, has bought more prominence to our top women's league and provided support to our clubs off the pitch as well as on."
The bank's head of marketing, Kevin Heavern said supporting local sport "is one of our absolute passions".
"Over the last number of years, we've seen such passion from the fans, coaches and players, and we've seen huge growth in the ladies' game, that meant extending our partnership for another three years was an easy decision," said Mr Heavern.
Since the first season of the Premiership in 2012-13 attendances in the league have grown 38%, with live television broadcasts of Premiership matches each season on BBC Two and Sky Sports.
