Of all the kingdoms of living organisms, the plant kingdom exhibits the greatest extremes of size and scale of individuals. From gigantic, massive organisms to extremely small ones, the plant species truly demonstrate the immense range of growth forms and size differences. Some record-holding plants are listed in this article; however, additional research may disclose new records of interest to botanists.

An individual plant of giant sequoia (Sequoiadendron giganteum) in Sequoia National Park, California, named the "General Sherman Tree" is considered to be the largest living plant, as well as the largest living thing on Earth.
