14 Biggest Trees in Oregon

Oregon is a beautiful state, and one of the reasons it’s so gorgeous is because of the plentiful trees in the state’s landscape. In fact, with nearly 31 million acres of forest in the state – covering almost half of it – you’re bound to find a lot of different magnificent trees.

Some trees listed below are very tall, while others are very wide and massive-looking. We’ve included the biggest trees regardless of why they’re called “big” in the first place, so if you love big trees, you’ve come to the right place.

Trees are truly nature’s wonders, and they do so much more than provide us with much-needed shade and dot the landscape with beauty. When you consider how old many of these trees are, they become even more amazing to look at.

You will be in awe once you realize that most of them will likely remain on Earth long after we’re gone. Below are 14 of Oregon’s biggest trees from small to biggest, and whenever possible, we’ve included the approximate or exact location in case you’d like to view them in person.
