Alysse (formerly HMS Alyssum) was one of the nine Flower-class corvettes lent by the Royal Navy to the Free French Naval Forces.

Shortly after midnight on 9 February 1942 while escorting convoy ON-60, Alysse was torpedoed by the German submarine U-654.

A further attempt was made to tow her to port later that day but after 18 hours Alysse foundered and sank at 6°34N/44°10W.
