Allium triquetrum is a bulbous flowering plant in the genus Allium (onions and garlic). It is known in English as three-cornered leek or three-cornered garlic, in Australia as angled onion and in New Zealand as onion weed. The name triquetrum refer to the three-cornered shape of the flower stalks.

Each stem produces 4-19 flowers in spring. The leaves have a distinct onion smell when crushed.

Allium triquetrum is native to south-western Europe, north-western Africa, Madeira and the Canary Islands, where it grows in meadows, woodland clearings, on river banks and roadside verges. It has also been introduced to Great Britain, Ireland, New Zealand, Turkey, Australia, the Unites States, and South America.

All parts of the plant, from the bulb to the flowers, are edible fresh or cooked.
