BAP Almirante Grau (CLM-81) was a De Zeven Provinciën-class light cruiser that served in the Dutch and Peruvian navies. Completed for the Dutch in 1953 as HNLMS De Ruyter (C801), she was acquired by Peru in 1973 and served as fleet flagship.

Almirante Grau underwent a major modernization program between 1985 and 1988 during which she was fitted with new weapons and electronics. She was the last gun cruiser in service in any navy before being decommissioned on 26 September 2017.

In 2019, it was to be said that she would be preserved as a museum ship. However, it was later announced on 14 February 2022 that the ship would put up for sale with an asking price of 4,180,000 soles (1,112,520 USD).^{[citation needed]}
