Jelly is a sweet or savoury food gel, usually through the addition of gelatin or pectin.

Sweet food gels include gelatin desserts such as Jell-O and blancmange or clear fruit jam which has gelled such as grape jelly, mint jelly or apple jelly. Concord grape jelly is usually used in the staple of school lunches, the peanut butter and jelly sandwich. In North America, the term is often used to mean jam in general, whether it has gelled or not. Jelly babies are a popular gelatine based confectionery in the UK and gummi bears are popular worldwide.

Savoury food gels include aspic or plain gelatine.

In beekeeping, royal jelly is a specific foodstuff made by bees which, when fed to bee larvae, turns them into queen bees.
