São Tomé Island League[1] is the top division of the São Toméan Football Federation for the São Tomé Island.

The champion competes at the national championships each year.

Before independence, it was the only regional competition in the nation.

It was the sole competition in the country and was acted as a national competition until 1985 when the Príncipe League were founded.

From 1986 to 1988, 1991, 1992 and 1994 to 1997 as the other island's competitions were not held, the island champions were also national champions.
