HMS Grafton (F80) was a Type 23 frigate of the Royal Navy. It was the ninth vessel to bear the name, and is named after the Duke of Grafton. In 2003, the ship was used in the ITV drama series Making Waves as the fictional Royal Navy warship Suffolk. In early 2004 the ship was deployed in the Persian Gulf. In July 2004, it was announced that Grafton would be one of three Type 23 frigates to be decommissioned by the end of 2006.
