北美雲杉（Picea sitchensis；英語：Sitka spruce）是雲杉屬下的一種常綠喬木，是雲杉屬的兩個基位物種之一。這種雲杉高度可達100米[2]，樹幹直徑超過五米，因此成為世界最高的雲杉和第五高的針葉樹（次於巨杉、加州紅木、考里松和西部紅杉）[3][4]。 北美雲杉寿命绵长，有一些个体已超700岁。因为北美云杉生长速度极快，年轻的北美云杉一年就能长1.5米（4.9英尺），不过在判断老年北美云杉时体大小并没有太大的意义[5]。因其对环境要求不高且生长迅速，北美云杉多用作木料和造纸材料。 參考文獻 ^ Farjon, A.

Picea sitchensis, the Sitka spruce, is a large, coniferous, evergreen tree growing to just over 100 meters (330 ft) tall, with a trunk diameter at breast height that can exceed 5 m (16 ft). It is by far the largest species of spruce and the fifth-largest conifer in the world (behind giant sequoia, coast redwood, kauri, and western redcedar), and the third-tallest tree species (after coast redwood and South Tibetan cypress). The Sitka spruce is one of only three species documented to exceed 100 m (330 ft) in height. Its name is derived from the community of Sitka in southeast Alaska, where it is prevalent. Its range hugs the western coast of Canada and the US and continues south into northern California.
