List of lifeboat disasters in Britain and Ireland

Many lives have been lost by lifeboat crews going to the aid of people and vessels in distress at sea and around the coasts of Britain and Ireland (UK, Ireland, Channel Islands and the Isle of Man), mainly but not exclusively in the service of the Royal National Lifeboat Institution (RNLI). More than 600 names are inscribed on the RNLI Memorial at RNLI HQ, Poole. Some losses predate the RNLI (founded in 1824).

In the 19th century, lifeboats were almost exclusively oar and sail powered. Self-righting boats had been developed but were not yet widely adopted.

During the 20th century many advances were made in safety and durability of lifeboats, including self-righting and motor power. Life jackets were continuously being improved.
