在托尔金（J. R. R. Tolkien）奇幻小说的中土大陆里，伊拉诺（Elanor）是一种呈星形的小黄花，别号「太阳之星」。伊拉诺和宁芙瑞迪尔（Cerin Amroth）都在罗斯洛立安（Lothlórien）的塞林安姆罗斯（Cerin Amroth）茂盛生长。在佛罗多·巴金斯（Frodo Baggins）的提议下，山姆·詹吉（Sam Gamgee）的长女取名为伊拉诺（美貌伊拉诺）。

This is a list of all fictional plants that appear in J. R. R. Tolkien's Middle-earth writings. Under the Species heading, only those that differ from real-world plants are included.

In Quenya, an Elven tongue devised by Tolkien, the general term for plants, as distinct from animals (kelvar), is olvar.
