Brenham is a classic American Pallasite meteorite from Kiowa County, Kansas, USA, first recognised in the late 19th century near Haviland. It is associated with the Haviland crater and the surrounding Brenham strewn field, one of the most famous Pallasite localities in the world. Classified as a Pallasite, PMG-an, Brenham represents Stony-Iron material containing both iron-nickel metal and olivine from an early differentiated asteroid. The Meteoritical Bulletin records Brenham as an approved Kansas meteorite with multiple historic synonyms linked to the Haviland area.

Brenham specimens can vary considerably in appearance, with some pieces rich in olivine crystals and others more metal-dominant. Cut and polished sections often reveal yellow to green olivine set within an iron-nickel matrix, while etched metal areas may show internal crystalline structure. Natural pieces may display weathered exterior surfaces from long terrestrial exposure in the Kansas environment. The associated Haviland crater is a small impact feature in Kiowa County, adding further context to Brenham’s recovery history.

Studying Brenham provides insight into Pallasite formation, Stony-Iron meteorite structure, and the complex mixing of metal and silicate material inside early planetary bodies. Its historic American provenance, crater association, large recovered masses, and presence in major collections make it one of the most recognisable Pallasites. For collectors, Brenham offers a strong combination of rarity, visual appeal, and scientific significance. Each specimen represents ancient asteroid material preserved as a mixture of metal and olivine, with a direct connection to one of the best-known meteorite localities in the United States.
