Foxe Basin is a shallow oceanic basin north of Hudson Bay, in Nunavut, Canada, located between Baffin Island and the Melville Peninsula. For most of the year, it is blocked by ice floes.

The nutrient-rich cold waters found in the basin are known to be especially favorable to phytoplankton and the numerous islands within it are important bird habitats, including Sabine's gulls and many types of shorebirds. Bowhead whales migrate to the northern part of the basin each summer.
