Baboosic Lake (buh-BOO-sik) is a 222 acre (90 ha) lake located on the border of Amherst and Merrimack, in Hillsborough County, New Hampshire. The lake drains into Baboosic Brook.

Baboosic is a "warm water lake" and supports fish species such as chain pickerel, largemouth bass, yellow perch, catfish, and many sunfish. During winter months the lake freezes and is suitable for ice fishing, ice skating and snowmobiling.

Baboosic was once a popular destination for vacationers who traveled via the long-gone Boston & Maine Railroad Manchester & Milford branch train.

A popular Jewish summer camp for children ages 8-15 is located on the lake, called Camp Young Judaea.
