William Watton-Roberts has been jailed for four years for having a supply of cocaine with a street value of around £17,000.
Police found more than 50 grams of the Class A drug at his home in August 2023.
The 35-year-old from Chester appeared in the Magistrate's Court in February 2025 and admitted possession with intent to supply.
He has been sentenced by the Royal Court this week.
Detective Constable Carla Garnier said: “The safety of our community is always at the forefront of the States of Jersey Police.
“We will do our utmost to prosecute anyone who imports and/or deals drugs in Jersey and bring those responsible before the courts.”
