Prince's Square, Heritage listed park in Launceston, Tasmania.

Prince's Square is a 1.25-hectare (3-acre) park featuring symmetrical pathways and ornamental gardens throughout its layout. At its center stands the Val d'Osne Fountain, surrounded by mature trees and open grassy areas that create a balanced garden design.

The site began as a clay pit between 1824 and 1828, supplying materials for local brick manufacturing in the region. It was converted into a parade ground in 1843 before eventually becoming a public park.

The square holds the city's highest concentration of churches: St John's (1824), Milton Hall chapel (1841), Chalmers' Presbyterian (1859), Christ Church (1883, now City Baptist) and Gospel Hall (1939), two with rectories facing the square. The name changed from St John's Square to Prince's Square in 1868, when the Duke of Edinburgh planted two oaks here amid a choir, candlelight and gas illumination.

The park sits in the south-central business area with several entry points accessible from the surrounding streets. Visitors will find public facilities including restrooms and drinking fountains distributed throughout the space.

The Val d'Osne Fountain at the center was purchased from the 1855 Paris Industrial Exhibition, marking the completion of Launceston's first municipal water system. This imported monument demonstrates the town's connection to modern European standards of that era.
