This is a list of flora of Utah, a state in the western United States, listed alphabetically by family. As of 2018^[update], there are 3,930 species of plants in Utah, with 3,128 of those being indigenous and 792 being introduced through various means.^[1]

Plants sorted by family

Each entry lists the scientific name first (sorted alphabetically), then one or more common names for the plant (if any). Flora that have been introduced to the state are indicated with an † at the right of the scientific name. Entries are otherwise native. Entries marked with ‡ are considered invasive or noxious per the official list of noxious weeds maintained by the Utah Department of Agriculture and Food, though nine of those are not known to exist in Utah and have therefore not been included here.^[2]
