Unihockey Prime League Men (also known as Lidl Unihockey Prime League Men due to sponsorship, abbreviated as L-UPL Men) is the top men's floorball league in Switzerland. The league consists of 12 teams. It was first played in the 1983–84 season.
The champion of the league is eligible to compete at the Champions Cup. The lower league is National League B.
The most successful team in the league, with 13 titles, the most recent in 2023, is SV Wiler-Ersigen. In the last 2024–25 season, the team Zug United won the championship for the second time.
Since its founding, the league was known as National League A (NLA). Between the 2007–08 and 2012–13 seasons, it was renamed Swiss Mobiliar League (SML) due to sponsorship, before reverting to NLA. The league adopted its current name in the 2022–23 season following a new sponsorship agreement.
The Superfinal, a single match deciding the championship title, was introduced in 2015.
