Avis Gertrude Dolphin (24 August 1902 in Rotherham, Yorkshire, England – 5 February 1996 in Meirionydd, Wales) was a survivor of the 7 May 1915 sinking of the RMS Lusitania after being torpedoed by an Imperial German Navy U-boat during the First World War.

Dolphin was on RMS Lusitania on her way to England, where she was to live with her grandparents and attend school, when she befriended author and professor Ian Holbourn.

The resulting list was so sudden and violent that dishes crashed off the tables; but she recalled the scene as one of "absolute calm".

She lived the remainder of her life in Snowdonia, Wales; dying of natural causes in Meirionydd at the age of 93 on 5 February 1996.
