Moore Creek (French: ruisseau Moore) is a creek in South Algonquin, Nipissing District in Northeastern Ontario, Canada. It is in the Saint Lawrence River drainage basin and is a left tributary of the Madawaska River.
Moore Creek begins at Cross Lake at an elevation of 441m (1,447feet) and travels 5km (03miles) southwest to McKenzie Lake at an elevation of 395m (1,296feet). The creek then flows north 6.5km (04miles) towards Moore Lake at an elevation of 380m (1,250feet), taking in the right tributary Coghlan Creek from Coghlan Lake along the way. Pastwa Creek from Pastwa Lake enters as a left tributary at Moore Lake itself. Finally, the Moore Creek heads 7km (04miles) north, passing under Ontario Highway 523, to its mouth at the Madawaska River, at an elevation of 314m (1,030feet). The Madawaska River flows via the Ottawa River to the Saint Lawrence River.
The creek is entirely in South Algonquin, Nipissing District, but part of the drainage basin, like the southern end of McKenzie Lake and some other tributaries flowing from the south, is in Hastings Highlands, Hastings County.
