Northbranch is an H5 Ordinary Chondrite found in Jewell County, Kansas, USA, in 1972. A single stone of around 76 kg was recovered from a grain field, though it was not formally recognised as a meteorite until 1997. As an H Chondrite, Northbranch contains relatively high iron compared with L and LL Chondrites, while its type 5 classification indicates significant thermal metamorphism on its parent asteroid. The Meteoritical Bulletin records Northbranch as an approved Kansas meteorite with H5 classification.

Northbranch specimens typically show the compact, equilibrated texture of an H5 Ordinary Chondrite, with subdued chondrules, metal grains, and silicate minerals that have been partly recrystallised by heat. Cut and polished pieces can reveal reflective metallic inclusions and a solid, stony matrix, while natural surfaces may show weathering from terrestrial exposure. The type 5 classification means that original Chondritic features are less distinct than in type 3 or 4 meteorites, but the material still preserves the overall character of an Ordinary Chondrite.

Studying Northbranch provides insight into the H Chondrite parent body, thermal metamorphism, and the preservation of meteorites in the Great Plains environment. Its Kansas provenance, substantial single-stone mass, and recognised classification make it especially appealing for collectors of USA meteorites and representative Ordinary Chondrites. Each specimen represents ancient asteroid material formed over 4.5 billion years ago, preserved as part of a valid American meteorite find.
