Del Norte Titan is a coast redwood (Sequoia sempervirens) tree in Del Norte County, Northern California, that was confirmed by measuring to be at least 23.7 feet (7.2 m) in diameter at breast height (DBH, measured 4.5 feet or 1.4 metres above soil grade), and 307 feet (94 m) tall.

Measured by botanist Stephen Sillett, it ranks as the world's fifth largest coast redwood.

Lost Monarch in the same park, is actually larger with more wood volume than Del Norte Titan, if basal stems are included.

The grove (unofficially named) is located in Jedediah Smith Redwoods State Park.

Their exact location was kept secret by arborists until 2011, when a visitor posted their geolocation online.
