St Joseph's Convent, Cairns, Religious heritage site in Cairns, Australia.

St Joseph's Convent is a two-storeyed reinforced concrete building with a rectangular plan and a return bay on the southern corner. Wide verandahs run around both levels, and a two-storeyed entrance portico with gabled roofs faces the lawn and mature trees on Abbott Street. It was designed by Edward Gregory Waters and built in 1912–14 by Wilson & Baillie.

The Sisters of Mercy established this convent between 1912 and 1914 under Bishop James Murray's direction. The building replaced two earlier cottages and marked the start of organized Catholic presence in the region.

The convent served as a center for Catholic education and care in early North Queensland, working alongside the nearby cathedral to shape the region's spiritual life. Its presence helped establish a network of religious services that families in Cairns relied upon for generations.

The convent stands well back from Lake Street behind a lawn with mature trees flanking a single-width concrete entrance path. The original fence along Lake Street is a low concrete wall with evenly spaced piers and "Cyclone" chain mesh panels, leading to a Gothic-styled reinforced concrete arched gate aligned with the main entrance door.

Bishop James Murray, who pushed for the convent's construction, died on 13 February 1914, five weeks before James Duhig, Archbishop of Brisbane, officially opened the building on 22 March 1914. The fence along Lake Street keeps its original "Cyclone" chain mesh panels between low concrete piers.
