A laurel wreath is a symbol of triumph, a wreath made of connected branches and leaves of the bay laurel (Laurus nobilis), an aromatic broadleaf evergreen. It was also later made from spineless butcher's broom (Ruscus hypoglossum) or cherry laurel (Prunus laurocerasus). It is worn as a chaplet around the head, or as a garland around the neck.

Wreaths and crowns in antiquity, including the laurel wreath, trace back to Ancient Greece. In Greek mythology, the god Apollo, who is patron of lyrical poetry, musical performance and skill-based athletics, is conventionally depicted wearing a laurel wreath on his head in all three roles.^{[citation needed]} Wreaths were awarded to victors in athletic competitions, including the ancient Olympics; for victors in athletics they were made of wild olive tree known as "kotinos" (κότινος), (sc. at Olympia) – and the same for winners of musical and poetic competitions. In Rome they were symbols of martial victory, crowning a successful commander during his triumph. Whereas ancient laurel wreaths are most often depicted as a horseshoe shape, modern versions are usually complete rings.^{[citation needed]}

In common modern idiomatic usage, a laurel wreath or "crown" refers to a victory. The expression "resting on one's laurels" refers to someone relying entirely on long-past successes for continued fame or recognition, whereas to "look to one's laurels" means to be careful of losing rank to competition.

Apollo, the patron of sport, is associated with the wearing of a laurel wreath. This association arose from the ancient Greek mythology story of Apollo and Daphne. Apollo mocked the god of love, Eros (Cupid), for his use of bow and arrow, since Apollo is also patron of archery. The insulted Eros then prepared two arrows—one of gold and one of lead. He shot Apollo with the gold arrow, instilling in the god a passionate love for the river nymph Daphne. He shot Daphne with the lead arrow, instilling in her a hatred of Apollo. Apollo pursued Daphne until she begged to be free of him and was turned into a laurel tree.

Apollo vowed to honor Daphne forever and used his powers of eternal youth and immortality to render the laurel tree evergreen. Apollo then crafted himself a wreath out of the laurel branches and turned Daphne into a cultural symbol for him and other poets and musicians.

In some countries, the laurel wreath is used as a symbol of the master's degree. The wreath is given to young masters at the university graduation ceremony. The word "laureate" in 'poet laureate' refers to the laurel wreath. For example, the greatly admired medieval Florentine poet and philosopher Dante Alighieri is often represented in paintings and sculpture wearing a laurel wreath.

In Italy, the term laureato is used in academia to refer to any student who has graduated. Right after the graduation ceremony, or laurea in Italian, the student receives a laurel wreath to wear for the rest of the day. This tradition originated at the University of Padua and has spread in the last two centuries to all Italian universities.^{[citation needed]}

At Connecticut College in the United States, members of the junior class carry a laurel chain, which the seniors pass through during commencement. It represents nature and the continuation of life from year to year. Immediately following commencement, the junior girls write out with the laurels their class year, symbolizing they have officially become seniors and the period will repeat itself the following spring.
