Frog Hollow is one of the neighborhoods of Hartford, Connecticut. It is a predominantly working-class residential area, bounded on the north by Capitol Avenue, the east by Lafayette Street, the south by Madison and Hamilton Streets, and on the west by Interstate 84. The neighborhood was developed between about 1850 and 1930, and still contains a remarkable concentration of residential housing from that period. The entire neighborhood, covering more than 150 acres (61 ha) and including more than 900 buildings, is listed on the National Register of Historic Places.
