Allium howellii is a North American species of wild onion known by the common name Howell's onion. It is endemic to California.

There is a single cylindrical leaf about as long as the stem. The inflorescence holds up to 100 dark-veined lavender to white flowers, each under a centimeter long. [2] [3] [4]
