Hvitträsk is a mansion complex in Kirkkonummi, Finland, about 30 kilometers (19 mi) west of Helsinki. It was designed as a studio home by the members of the Finnish architecture firm Gesellius, Lindgren, Saarinen, later becoming the private residence of Eliel Saarinen. It currently operates as a museum.

The development was started when the plot was purchased by the company in 1901. The construction was mostly completed by 1903.^[1][2][3][4] The house was named after Lake Vitträsk [fi], beside which it was built. [H]vitträsk literally means White Lake. Today Hvitträsk is a museum open to the public. The red-roofed manor structure facing the lake is the main museum building, and the brownish structure separated on the other side by a yard is the cafeteria. There is also a smaller sauna down by the lake.^[5]

In 1922 Lindgren's home in the north side partially burned down. Eliel Saarinen's son Eero Saarinen designed a new building in its place in 1929–33.^[5][1][6]
