Vækerø Gård is a historic farm and the sight of an old manor house in the district of Vækerø in Oslo, Norway. The manor is a large brick building constructed during 1880 after drawings by Herman Schirmer (1845-1913), the son of noted Norwegian architect, Heinrich Ernst Schirmer. He established its own architectural practice in Christiania in 1869 and was also a teacher at the Oslo Drawing School (Tegneskolen i Kristiania).
The manor was formerly a part of a larger estate property related to Bærums Verk. The manor belonged to the Løvenskiold family but was later sold to Norsk Hydro.
