Scallions (also known as green onions, spring onions, salad onions, table onions, green shallots, onion sticks, long onions, baby onions, precious onions, yard onions, gibbons, or syboes) are the edible plants of various Allium species, all of which are "onion-like", having hollow green leaves and lacking a fully developed root bulb.
The words scallion and shallot are related and can be traced back to the Greek askolonion as described by the Greek writer Theophrastus. This name, in turn, seems to originate from the name of the town of Ashkelon. The shallots themselves apparently came from farther east of Europe.
The Welsh onion (Allium fistulosum) does not form bulbs even when mature, and is grown in the West almost exclusively as a scallion or salad onion, although in Asia this species is of primary importance and used both fresh and in cooking. "Scallion" is also used for young plants of the common onion (A. cepa var. cepa) and shallot (A. cepa var. aggregatum, formerly A. ascalonicum), harvested before bulbs form, or sometimes when slight bulbing has occurred. Most of the cultivars grown in the West primarily as salad onions or scallions belong to A. cepa var. cepa. Other species sometimes used as scallions include A. ×proliferum and A. ×wakegi.
Species and cultivars which may be called "scallions" include:
- Allium cepa
- 'White Lisbon'
- 'White Lisbon Winter Hardy' - an extra-hardy variety for overwintering
- Allium chinense
- Allium fistulosum
- A. ×proliferum
- Allium ×wakegi
Harvested for their taste, they are milder than most onions. They may be cooked or used raw as a part of salads, salsas, or Asian recipes. Diced scallions are used in soup, noodle and seafood dishes, as well as sandwiches, curries or as part of a stir fry. In many Eastern sauces, the bottom half-centimetre (quarter-inch) of scallion roots is commonly removed before use.
In Catalan cuisine, calçot is a variety of green onion traditionally eaten in a calçotada (plural: calçotades). A popular gastronomic event of the same name is held between the end of winter and early spring, where calçots are grilled, dipped in salvitxada or romesco sauce, and consumed in massive quantities. 
In Vietnam, Welsh onion is important to prepare dưa hành (fermented onions) which is served for Tết, the Vietnamese New Year. A kind of sauce, mỡ hành (Welsh onion fried in oil), is used in dishes such as cơm tấm, bánh ít, cà tím nướng, and others. Welsh onion is the main ingredient in the dish cháo hành, which is a rice porridge dish to treat the common cold.
In southern Philippines, it is ground in a mortar along with some ginger and chili pepper to make a native condiment called wet palapa, which can be used to spice up dishes, or topped in fried or sun dried food. It could also be used to make the dry version of palapa, which is stir fried fresh coconut shavings and wet palapa.
