The Ducasse d'Ath is a traditional folk festival held in Ath, Hainaut, Belgium, to mark the victory of David over Goliath.

The parade is held annually on the fourth Sunday of August and is characterised by the presence of processional giants depicting the horse Bayard and several other characters from local history.

It is a procession or ducasse[A] with act of "circumambulation" around a religious symbol (e.g. a statue of the city's patron saint), in Latin circumambulatio or amburbium,[6] which can be found in many religions and beliefs.

[8] In 2008, the Ducasse d'Ath was recognised as one of the Masterpieces of the Oral and Intangible Heritage of Humanity by UNESCO, as part of the bi-national inscription 'Processional giants and dragons in Belgium and France'.

[4] It was delisted in December 2022 following complaints about one of the characters that appears in the procession: a 'savage', depicted by a white person in blackface, wearing a nose ring and chains.
