Royal Hollandais was a 90-gun Chatham-class ship of the line.

Built for the Batavian Navy as De Ruyter and renamed Koninklijke Hollander after the establishment of the Kingdom of Holland in 1806, the ship was incorporated in the French Navy as Royal Hollandais when the First French Empire annexed the country.

In 1811, that name was shortened to Hollandais.

On 10 July, she was appointed to Édouard Thomas Burgues de Missiessy's squadron.

[1] She was returned to the Royal Netherlands Navy in 1814 and was decommissioned in 1819.
