Pinus pseudostrobus, known in English as the smooth-bark Mexican pine and in Spanish as chamite or pacingo, is a tree found in forests of Mexico and Central America. ^{[1] [2] [6] [ citation needed ]} It is 8 to 25 m tall with a dense and round top.^{[ citation needed ]}It is threatened by logging and wood harvesting. ^[1] The bark is brown and fissured and smooth when young. ^{[ citation needed ]} It is subject to ex situ conservation. ^[1] It grows at altitudes between 850 and 3250 m. from 26° to 15° north latitude, from Sinaloa, Mexico to Nicaragua and Honduras. It occurs within a rainfall regime that rains mostly in summer.^{[ citation needed ]}

In some forested areas like southern Nuevo León Pinus pseudostrobus is the tree with largest volume per hectare. ^[7]

English botanist John Lindley described the species in 1839. It is divided into Pinus pseudostrobus var.apulcensis (Lindl.)Shaw (Apulco pine), Pinus pseudostrobus f.protuberans Martínez and Pinus pseudostrobus var.pseudostrobus. ^{[2] [6]}

It has been introduced in New Zealand near sea level and has done well.^{[ citation needed ]}
