The Blue Mountain Creek, an intermittent stream that is part of the Macleay River catchment, is located in the Northern Tablelands region of New South Wales, Australia.

Blue Mountain Creek rises on the eastern slopes of Blue Mountain, north northeast of Walcha and south southeast of Uralla, within the Great Dividing Range. The river flows generally east, joined by two minor tributaries before reaching its confluence with the Macleay River in the remote country within the Oxley Wild Rivers National Park, upstream of the confluence of the Macleay and Chandler rivers. The river descends 838 metres (2,749 ft) over its 41 kilometres (25 mi) course.
