Fiesta San Antonio is an annual festival held in April in San Antonio, Texas, and is the city's signature event since 1891. The festival, also known as the Battle of Flowers, commemorates of the Battle of the Alamo, which took place in San Antonio, and the Battle of San Jacinto, which led to Texas' independence from Mexico in April 1836.

A flower parade is a parade in which the floats, vehicles, boats, participants, animals and other things are decorated or covered in flowers. Often there are other elements like marching bands and people in costumes. Flower parades are held in several countries, many of which celebrate the forthcoming of the seasons. The oldest flower parade dates back to the 1800s.
