Our Lady of the Sacred Heart Church, Thursday Island, Catholic church on Thursday Island, Australia.

Our Lady of the Sacred Heart Church stands at 120 Douglas Street and features Gothic Revival architecture with a gabled roof and timber frame construction. The interior contains one large rectangular space divided into a nave and sanctuary.

Three Missionaries of the Sacred Heart priests arrived at Thursday Island on 24 October 1884 and bought land in Port Kennedy in January 1885, where a small church was erected by February 1886. Whether the present church is that c. 1885 building is unsubstantiated; photographs suggest its current form and concrete footings date from about 1905. From 1884 to 1889 the mission was the departure point for Catholic missions to British New Guinea.

The interior features stained glass windows and wall paintings created by David Sing in 1935 using trompe-l'oeil techniques that trick the eye. These artworks continue to define the visual character of the worship space today.

The main entrance on Douglas Street provides access to the building, and visitors can easily appreciate the timber frame construction and structural details from outside. Allow time to examine the interior furnishings and artistic elements carefully.

Whether the present church is the small iron church erected by February 1886 is not substantiated; photographic evidence suggests it had acquired its present form and concrete footings by about 1905. The mission's first Masses were held at McNulty's Hotel, later the Federal Hotel, for a congregation of mostly Filipino pearl-shell fishers known as Manila Men.
