松柏门是植物界里13或14个门之中的一个，属于裸子植物，为结有松果的维管束植物；其中所有已灭绝的物种都是木本植物，现存的大部份是树木，但有少部份为灌木。典型的松柏门植物包含有香柏、柏、花旗松、冷杉、刺柏、贝壳杉、落叶松、松、红杉、云杉和红豆杉等 。松柏门约有8科、68属且630个现存物种。松柏门的物种可以在世界上几乎所有的地方上发现其自然生长的踪迹，且通常会在其栖息地内成为优势物种，如在泰加林里。松柏门有很大的经济价值，主要用做木材和纸张的生产；松柏门的木材称之为软木。

The conifers, division Pinophyta, also known as division Coniferophyta or Coniferae, are one of 12 extant division-level taxa within the Kingdom Plantae (Viridiplantae) and 10 within the extant land plants. Pinophytes are gymnosperms, cone-bearing seed plants with vascular tissue. All extant conifers are woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews. As of 1998, the division was estimated to contain eight families, 68 genera, and 629 living species.
