Botanic Gardens is a public garden in Belfast, Northern Ireland.

Stranmillis is an area in south Belfast, Northern Ireland. It is also an electoral ward for Belfast City Council, part of the Laganbank district electoral area. As part of the Queen's Quarter, it is the location for prominent attractions such as the Ulster Museum and Botanic Gardens. The area is located on Stranmillis Road, with Malone Road to the west and the River Lagan to the east. Its name, meaning "the sweet stream" in Irish, refers to the Lagan, whose waters are still fresh at this point, before becoming brackish as the river flows onward toward its mouth in Belfast Lough.
