Captain Charles Jones, 5th Viscount Ranelagh (29 October 1761 – 20 December 1800) was a British Royal Navy officer and Irish peer of the late-eighteenth century who served on the Ireland station in HMS Doris but died aged 39 from an illness during his military service.

The son of Charles Wilkinson Jones, 4th Viscount Ranelagh and his wife Sarah Montgomery (daughter of Irish politician Thomas Montgomery), Jones was raised in Dublin and attended Trinity College, Dublin before joining the Royal Navy.

[1] Jones was appointed in 1795 to HMS Doris and attached to the Irish station during the French Revolutionary Wars.

Fraternité was the flagship of the French attempt to invade Bantry Bay and by driving her off, the invasion force was left leaderless and was dispersed and defeated piecemeal.

[1] In 1798, Doris was again involved in foiling a French attempt to invade Ireland, forming part of a squadron under Sir John Borlase Warren.
