The heavyweight contenders battling to be crowned during America’s Fat Bear Week have been announced.
The much-loved contest, running from September 22 to 29, pits the brown bears of Alaska‘s Katmai National Park & Preserve against each other as they bulk up for winter hibernation.
A total of 11 adult bears are competing this year, ranging from formidable former champions to hungry newcomers hoping to seize the crown.
They include a gigantic male with a permanently broken jaw, a fiercely protective mother and an aging former king of the river attempting a remarkable comeback.
Wildlife fans around the world will decide their fate by voting for the bear they believe best represents fatness and survival success.
Each head-to-head winner will advance through the single-elimination tournament until the final two face off.
The online competition has transformed Katmai’s bulkiest residents into international celebrities while showcasing the astonishing preparations they make for Alaska’s brutal winter.
But when the final votes are counted on September 29, only one heavyweight will be named the 2026 Fat Bear Week champion.
This young adult male has milk chocolate colored fur in late summer. His ears are oval-shaped and his muzzle arcs slightly up toward the tip of his nose
This large adult female has medium-brown fur, blond ears, and a prominent shoulder hump
This medium-sized adult female has round ears and grizzled brown fur on her neck and back. Her claws are dark in color but paler toward their tips
Katmai is home to some of the largest brown bears on Earth, with the biggest males exceeding 1,200 pounds by fall.
The bears owe much of that dramatic transformation to the sockeye salmon that fill Brooks River between late June and October. They spend the season feasting to accumulate enough fat to survive months of hibernation without eating or drinking.
This year’s most dramatic contender may be 32 Chunk, an enormous, dark-brown male with a scarred muzzle and a broken jaw that will never fully heal.
The injury, believed to have occurred during a fight, hampered his ability to catch salmon. However, Chunk learned to eat without full use of his lower jaw and remains among the river’s largest bears.
He faces stiff competition from 128 Grazer, a large female with blond ears and a fearsome reputation for protecting her cubs. Grazer won the contest in 2023 and became the first mother bear to claim the title in 2024.
Bear 26 is another mother making her Fat Bear Week debut. After losing her first litter in 2023, she returned with new cubs and kept them away from riskier sections of the river.
She is also believed to be the daughter of 435 Holly, one of Brooks River’s most famous bears and a former Fat Bear Week champion.
Another newcomer, Bear 99, is a young, milk-chocolate-colored male who has grown large enough to challenge older bears for productive fishing positions at Brooks Falls.
This large adult female has grizzled-brown fur. While fishing the lip of the falls, 910 occasionally throws her head upward, a behavioral tic that may be tied to the anticipation of catching salmon
This large adult male has uniformly grizzled-brown fur. His ears are wide-set and the fur on the middle of his forehead is often neatly parted
This large adult male has uniformly brown body fur and light-brown ears. When 856 stands on all four legs, he is likely more than five feet tall at the shoulders
Chunk is a large adult male with narrowly-set eyes, dark brown fur, and a prominent brow ridge. He has a distinctive scar across his muzzle and a broken, yet healing jaw
Bear 503 was adopted by Holly after becoming separated from his mother as a yearling. He is now a towering male known for succeeding without always relying on brute force.
Then there is 602, a dominant male who became one of the river’s most familiar faces this summer. He frequently lounged or slept in the water between meals, earning the nickname ‘floatato,’ and performs a peculiar stomping dance when excited.
At nearly five years old, female Bear 609 is striking out independently after spending longer than usual with an adoptive family.
The 2022 Fat Bear Junior champion is already considered large for her age and has demonstrated impressive fishing skills.
This is a medium-sized and fat adult female. Bear 901 has blond-rimmed, triangular ears. Her fur is golden brown in early summer and grizzled brown in late summer
This large and tall adult male has grizzled-brown body fur. His ears are light brown and crescent or apostrophe-shaped when viewed from the front or back
This nearly five-year-old female bear has uniformly brown body fur with grizzled fur on her face, ears, and neck. She has large round ears, a narrow muzzle, and a prominent and conical shoulder hump
Grazer is a large adult female with a long straight muzzle and conspicuously blond ears. She has grizzled, light brown fur in late summer and fall
One of the oldest contenders is 856, a huge male who dominated the Brooks River hierarchy from 2011 to 2023.
Now in his mid-20s, he has adapted to younger rivals by avoiding fights he is unlikely to win while continuing to challenge bears when the odds favor him.
The female field also includes 901, a consistently plump bear whose substantial fat reserves could prepare her for another chance at motherhood after her first litter died.
Sisters 909 and 910 complete the lineup. Both are daughters of 409 Beadnose, the beloved bear crowned champion in 2018, and both have inherited their mother’s skill at catching salmon from the lip of Brooks Falls.
Bear 909 was seen with three cubs in May, but none remained by June. Meanwhile, 910 spent her first summer alone since 2021 after raising two young bears, including her adopted niece 609.
Fat Bear Week began as Fat Bear Tuesday in 2014 before expanding into a weeklong tournament the following year. Fans can watch the animals through live cameras, study their transformations and vote online each day from noon to 9 p.m. Eastern Time.
