A group of islands off of the Connecticut coast.

The islands themselves - long prized by sailors on the Sound as a sheltered deep-water anchorage - comprise 23 that are inhabited (most of them wooded), numerous barren rocks and hundreds of reefs visible only at low tide.

Although they are said to be named for the thimbleberry, a relative of the black raspberry, that plant is seldom seen in the area, and is more frequent in northern New England. Other species of blackberry and raspberry, however, are sometimes referred to by residents of the area as thimbleberries.
