Allium ampeloprasum is a member of the onion genus Allium. The wild plant is commonly known as wild leek or broadleaf wild leek. Its native range is southern Europe to western Asia, but it is cultivated in many other places and has become naturalized in many countries.

Allium ampeloprasum is regarded as native to all the countries bordering on the Black, Adriatic, and Mediterranean Seas from Portugal to Egypt to Romania. In Russia and Ukraine, it is considered invasive except in Crimea, where it is native. It is also native to Ethiopia, Uzbekistan, Iran and Iraq. It is considered naturalized in the United Kingdom, Ireland, the Czech Republic, the Baltic States, Belarus, the Azores, Madeira, the Canary Islands, Armenia, Azerbaijan, Pakistan, China, Australia (all states except Queensland and Tasmania), Mexico, the Dominican Republic, Puerto Rico, Haiti, the United States (southeastern region plus California, New York State, Ohio and Illinois), Galápagos, and Argentina.<ref>Kew World Checklist of Selected Plant Families, Allium ampeloprasum</ref><ref name="laksdf909wer9">Flora of North America v 26 p 238, Allium ampeloprasum'</ref><ref>BONAP (Biota of North America Program) floristic synthesis, Allium ampeloprasum'</ref><ref>Flora of China v 24 p 200, Allium porrum</ref><ref>Altervista, Schede di Botanica</ref>
