Allium tribracteatum, known by the common name Threebract onion, is a species of wild onion.
This is a small onion plant producing a stem only a few centimeters long from an oval-shaped bulb. There are two leaves which are usually much longer than the stem. The inflorescence contains up to 30 petite white to purple flowers, each less than a centimeter long.
Allium tribracteatum is endemic to California, where it is known only from the slopes of the Sierra Nevada in Tuolumne and Calaveras Counties.
