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] It is 8 to 25 m tall with a dense and round top.It is threatened by logging and wood harvesting.[1] The bark is brown and fissured and smooth when young. 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.

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.
