St John Street is a main north-south street located in the city of Launceston, Tasmania. St John Street starts at the Esplanade (former Queens Wharf) and runs roughly SSE for 1.8 km to where it terminates on Howick Street on the border with South Launceston. St John Street serves as one of two 'high streets' in the city and runs past many of the city's most iconic and important buildings. The street is notably broken twice in its southernmost length between Frankland and Howick Street where the street runs over a ridge whereby the terrain was too steep for vehicular traffic to use safely resulting in portions of the street being utilized as pedestrian only reserves and only accessible to vehicles via French Street.
