The 2025 Veikkausliiga was the 95th season of top-tier football in Finland, which takes place from April to November. Veikkaus was the league's sponsor.
The league consisted of twelve teams; ten teams remaining from the previous season, and two teams promoted from the Ykkösliiga. KuPS entered the season as defending champions.
The promoted teams were the 2024 Ykkösliiga champions KTP (returning to the top flight after a single-season absence), and 2024 Veikkausliiga play-off winners Jaro (returning to the top flight after a nine-year absence). They replaced the 2024 Veikkausliiga bottom-placed team EIF (relegated after a single season), and Veikkausliiga play-off losers Lahti (relegated after a 13-year stint in the top flight).
All teams are obligated to have the Veikkausliiga logo on the right sleeve of their shirt.
