Terrific Street was a short-lived entertainment district on San Francisco's Barbary Coast during the early 20th century. It consisted of dance halls, jazz clubs, and various kinds of drinking establishments. Terrific Street was centered upon a single block of Pacific Street, which was one of the earliest streets to cut through the hills of San Francisco, starting near Portsmouth Square and continuing east to the first shipping docks at Buena Vista Cove.

The early decades of the Barbary Coast were marred by persistent lawlessness, gambling, administrative graft, vigilante justice, and prostitution. The Barbary Coast's most violent and vice-ridden days occurred between the 1860s to the 1880s, when its theft, harassment issues, and violence caused most San Franciscans to avoid the area. However, with the passage of time San Francisco's government gained strength and competence, and the Barbary Coast's maturing entertainment scene of dance halls and jazz clubs later influenced America's culture.
