The Biggest Tree in Oklahoma
How Oklahoma Determines Its "Largest" Trees
Oklahoma's champion trees are ranked using a standardized points system managed by the Oklahoma Forestry Services and the Oklahoma Forestry Association. The formula is simple yet effective:
Total Points = Circumference (inches at breast height) + Height (feet) + (Average Crown Spread in feet ÷ 4)
This system emphasizes overall size, giving credit to trees with massive trunks (like cottonwoods) while also rewarding height and spread. The state maintains an official registry of nearly 100 champion and co-champion trees across dozens of species. The list is updated periodically, with the most recent comprehensive data from 2014 and refinements in recent years.
These aren't just the tallest trees—they're the largest by volume and presence. And yes, Oklahoma's largest tree holds the top spot with an impressive 448 points!
Meet the Largest Tree in Oklahoma: The Eastern Cottonwood Champion
Currently Oklahoma's largest tree, is a magnificent Eastern Cottonwood (Populus deltoides) located in Woodward County, near the town of Woodward in northwest Oklahoma.
This behemoth stands out with:
- Circumference: 326 inches (that's over 27 feet around the trunk!)
- Height: 98 feet
- Crown Spread: 94 feet
- Total Points: 448
Native to Oklahoma's river valleys and floodplains, Eastern Cottonwoods are fast-growing giants that thrive in the state's variable climate. This champion, measured in recent years, edges out competitors thanks to its enormous girth. It's a true symbol of Oklahoma's resilient natural heritage, providing shade, wildlife habitat, and a stunning sight for anyone lucky enough to glimpse it.
While exact public access to this private property tree isn't always straightforward, enthusiasts often catch views from nearby roads or during guided nature tours in the area. If you're road-tripping through western Oklahoma, keep an eye out—cottonwoods like this one dominate the landscape along the Canadian River.
The Historic Giant: Oklahoma's Legendary Bald Cypress
No discussion of the biggest tree in Oklahoma is complete without honoring the state's most famous former champion: a colossal Bald Cypress (Taxodium distichum) that once held the title.
Located near Eagletown in McCurtain County (southeast Oklahoma), this tree was legendary in the mid-20th century. At its peak, it measured:
- Over 32 feet in circumference
- 118 feet tall
- Nearly 100 feet in crown spread
Tragically, it was struck by lightning and destroyed in 1982. Locals still share stories of this "Giant Cypress," which drew visitors from across the region.
But the bald cypress story isn't over! Oklahoma's current state champion bald cypress thrives in the Little River National Wildlife Refuge, also in McCurtain County. This living giant boasts:
- Circumference: 292 inches
- Height: 128 feet (making it one of the tallest trees in the state)
- Crown Spread: 77 feet
- Total Points: 439
It's the second-largest tree overall and offers a glimpse into what Oklahoma's ancient forests once looked like. The refuge is open to the public—perfect for a day of birdwatching and tree-gazing.
