Thorne Bay is a city in Prince of Wales-Hyder Census Area, Alaska, United States.

In the 1960s and 1970s it was the largest logging camp in North America and was host to over 1500 residents at its peak.

It became a second-class city in 1982 and in 2001 the logging company pulled out having been a victim of breach of contract from the U.S. Forest Service.

[citation needed] The U.S. Forest Service signed a fifty-year contract in 1954 guaranteeing 150 million board foot (350 thousand m3) per year for the pulp mill and sawmills in Ketchikan.

[citation needed] By 1990 that figure was down to approximately 50 million board foot (120 thousand m3) per year.

Currently Thorne Bay features many seasonal residents and an employment sector based primarily in Forest Service and public education.

Thorne Bay also has the world's largest tree grapple, which is known as "the claw".

The grapple sits in front of the small town with a sign that says "Thorne Bay".
