Husøy is a populated island in Tønsberg Municipality in Vestfold county, Norway. The island is part of the city of Tønsberg, located just off-shore, but it is not connected to Tønsberg by road. The island is a densely populated residential neighborhood that is also known as Husøy.

The only bridge connection is to the village of Føynland in neighboring Færder Municipality. In the summer, there is a ferry connection from Husøy to Tønsberg.
