August Bournonville (21 August 1805 – 30 November 1879) is a Danish ballet master and choreographer.

August wais the son of Antoine Bournonville, a dancer and choreographer trained under the French choreographer, Jean Georges Noverre, and the nephew of Julie Alix de la Fay, née Bournonville, of the Royal Swedish Ballet.

August is born in Copenhagen, Denmark, where his father had settled.

He studies under the Italian choreographer Vincenzo Galeotti at the Royal Danish Ballet, Copenhagen, and in Paris, France, under French dancer Auguste Vestris.

He initiates a unique style in ballet known as the Bournonville School.

Following studies in Paris as a young man, August becomes solo dancer at the Royal Ballet in Copenhagen.

From 1830 to 1877, he is choreographer for the Royal Danish Ballet, for which he creates more than 50 ballets admired for their exuberance, lightness, and beauty.

He creates a style that, although influenced from the Paris ballet, is entirely his own.

As a choreographer, he creates a number of ballets with varied settings that range from Denmark to Italy, Russia to South America.

A limited number of these works have survived.

Bournonville's work becomes known outside Denmark only after the Second World War.

Since 1950, The Royal Ballet has several times made prolonged tours abroad, not the least to the United States, where they have performed his ballets.

Bournonville's best-known ballets are La Sylphide (1836), Napoli (1842), Le Conservatoire (1849), The Kermesse in Bruges (1851) and A Folk Tale (1854).
