'''''Pinus engelmannii''''', commonly known as the '''Apache pine''', is a [[tree]] of Northern [[Mexico]], in the [[Sierra Madre Occidental]] with its range extending into the Southwestern [[United States]]. This [[pine]] is a medium-sized species with a height of {{convert|20|–|30|m|abbr=off}} and a trunk diameter of {{convert|35|–|80|cm|0|abbr=off}}.

The branches are sparse and very stout, giving the tree a distinct appearance. The needles, among the longest of any pine, are in bundles of three (occasionally five), {{convert|20|–|40|cm|0|abbr=on}} long, stout, and spreading to slightly drooping. The cones are {{convert|8|–|16|cm|frac=4|abbr=on}} long, green or purple when growing, maturing glossy brown, moderately oblique with stoutly spined scales on the outer side (facing away from the branch). The Apache pine sometimes shows a grass stage like the related [[Michoacan pine]] (''P. devoniana'') and also [[longleaf pine]] (''P. palustris'').

The English name refers to the species' occurrence in the lands of the [[Apache Tribe|Apache]] [[Native Americans in the United States|Native Americans]], while the scientific name commemorates the pioneering American botanist [[George Engelmann]] who discovered the species in 1848. Engelmann first named the species ''Pinus macrophylla'', but this name had already been used for another pine, so it had to be renamed; this was done by the French botanist Carrière, who chose to honour Engelmann.

Apache pine was sometimes treated as a variety of ponderosa pine in the past (as ''[[Pinus ponderosa|P. ponderosa]]'' var. ''mayriana''), but it is now universally regarded as a distinct species.
