The 2018–19 Korisliiga season was the 79th season of the top professional basketball league in Finland. Karhu successfully defended their title to repeat as Finnish national champions.
The eleven teams played four times against each one of the other teams for a total of 40 games. The eight best qualified teams joined the playoffs and the last one played a best-of-three relegation playoff against the First Division runners-up.
Ura promoted from First Division and Kobrat remained in the league as Espoo United was expelled due to financial irregularities.[1] [2]
