Antoine Raymond Joseph de Bruni d'Entrecasteaux () (8 November 1737 – 21 July 1793) was a French naval officer, explorer and colonial governor. He is perhaps best known for his exploration of the Australian coast in 1792, while searching for the La Pérouse expedition. Antoine Bruni d'Entrecasteaux is commonly referred to simply as Bruni d'Entrecasteaux or Bruny d'Entrecasteaux, which is a compound surname (derived from his father's surname, Bruni and the family's origins in Entrecasteaux).
