Sullivans Creek, a partly perennial stream of the Murrumbidgee catchment within the Murray–Darling basin, is located in Canberra, Australian Capital Territory, Australia.

Sullivans Creek rises close to the border between the Australian Capital Territory (ACT) and New South Wales, north-east of Kenny, and north-west of Watson.

[3] Sullivans Creek flows generally south-west, through a small channel within a much larger older gully system in its upper reaches; and through a series of urban sealed stormwater channels in its middle reaches; before reaching the grounds of the Australian National University, towards its confluence with the Molonglo River near Acton.

Within the grounds of the Australian National University, the creek's original course has been altered to accommodate growth of the campus and enhance the natural landscape.

[5] After flooding was caused by heavy rains in 2018, all of the books on the lower levels of the ANU's Chifley Library were destroyed by the overflow.
