Which Canadian peninsula lies between Hudson Bay and the Labrador Sea and gives Labrador its name?

The Labrador Peninsula lies between Hudson Bay and the Labrador Sea and gives Labrador its name.

Also called the Quebec–Labrador Peninsula, it occupies much of eastern Canada. Quebec covers its western portion, while the province of Newfoundland and Labrador includes its eastern region. The peninsula is bounded by Hudson Bay and James Bay to the west, Ungava Bay and Hudson Strait to the north, and the Labrador Sea to the east.

The Labrador Peninsula is part of the Canadian Shield, an ancient area of exposed Precambrian rock. Its interior contains extensive boreal forest, wetlands, lakes, and tundra, with the Torngat Mountains along the northeastern coast.

The name Labrador is also used for the mainland portion of Newfoundland and Labrador province. It should not be confused with the separate Ungava Peninsula, which forms the northern part of Quebec between Hudson Bay and Ungava Bay.
