The Red Creek Fir is a large Douglas fir (Pseudotsuga menziesii) tree located in the San Juan Valley of Vancouver Island in British Columbia, Canada.

By volume, it is the largest known Douglas fir tree on Earth.

It flourished due to its location on the shaded southern slopes of the San Juan Valley and being no more than 0.5 km (0.31 mi) from the San Juan River.

[citation needed] Despite various attempts by the Ancient Forest Alliance, it does not yet have formal governmental protection aside from being placed on a public recreation site.

[4] A proposal exists to extend the current Pacific Rim National Park down the west coast of the island to include the Red Creek Fir, as well as it being listed by Heritage BC.
