Crater Creek is a tributary of Ksi Sii Aks (formerly "Tseax River") and part of the Nass River watershed in northern part of the province of British Columbia, Canada.

It flows generally south and west for roughly 25 km (16 mi) to join Ksi Aii Aks, which flows into Nass River near the community of Gitlaxt'aamiks (formerly "New Aiyansh"). Crater Creek's watershed covers 104 km2 (40 sq mi), and is mostly within the Nisga'a Memorial Lava Bed Protected Area and Nisga'a Memorial Lava Bed Provincial Park. The creek's mean annual discharge is estimated at 4.21 m3/s (149 cu ft/s).

The mouth of Crater Creek is located about 122 km (76 mi) northeast of Prince Rupert, British Columbia, about 425 km (264 mi) northwest of Prince George, British Columbia, about 170 km (110 mi) east of Ketchikan, Alaska; about 760 km (470 mi) north of Vancouver, British Columbia, and about 485 km (301 mi) southeast of Juneau, Alaska. Crater Creek's watershed's land cover is classified as 45.5% conifer forest, 25.5% barren, 14.0% shrubland, and small amounts of other cover.

Crater Creek lies within the traditional territory of the Nisga'a First Nation. Most of the creek's drainage is in Nisga'a Memorial Lava Bed Provincial Park (Nisga'a: Anhluut'ukwsim Lax̲mihl Angwinga'asankswhl Nisg̲a'a), which was included in the Nisga'a Treaty in 2000. It was the first provincial park in British Columbia to be jointly managed by the government and a First Nation.
