Gömmaren ( Swedish: literary "The Hider") is a small lake located in the municipality Huddinge in southern Stockholm, Sweden. It is the easternmost lake in the Tyresån Lake System.
The lake empties to the west through Gömmarbäcken ("Gömmaren Rill") and to the east through Fullerstaån ("Fullersta Stream"), which is further downstream guided in culverts under the commercial centre of Huddinge (Huddinge Centrum) before flowing south-east to empty into Lake Trehörningen. Motorboats are not allowed on the lake. Its clear water makes it popular for various open-air activities such as angling and bathing in summer, and skating in winters as it is one of the first lakes in Huddinge to freeze. Bathing from cliffs surrounding the lake is popular, but a sand beach is also available. A local fishing society (Långsjön-Gömmarens Fiskevårdsförening) is managing lake conservation and supply the general public with fishing permits.
