Plainview (1917), often referred to as Plainview (a), is an H5 Ordinary Chondrite found near Plainview in Hale County, Texas, USA, in 1917. It is one of several distinct meteorites recovered from the Plainview area, with later finds such as Plainview (1950) and Plainview (d) representing separate meteorites rather than a single paired fall. As an H Chondrite, Plainview (1917) contains relatively high iron compared with L and LL Chondrites, while its type 5 classification indicates significant thermal metamorphism on its parent asteroid.

Plainview (1917) specimens typically show the compact texture of an H5 Ordinary Chondrite, with a grey to brown stony matrix, metal grains, and subdued chondrules. It is also described as brecciated, with some sources noting carbonaceous inclusions and a total iron content of around 27 percent. The large recovered mass, reported at around 700 kg in several catalogues, makes Plainview (1917) one of the more substantial American Chondrite finds.

Studying Plainview (1917) provides insight into the H Chondrite parent body, thermal metamorphism, brecciation, and the preservation of Ordinary Chondrites in the Texas plains. For collectors, it offers a classic American meteorite with strong provenance, substantial known mass, and a recognised classification. Each specimen represents ancient asteroid material formed over 4.5 billion years ago, preserved as part of one of the best-known Texas meteorite finds.
