Melesina is a rare English feminine given name of uncertain origin, though it is likely a diminutive or variant of Millicent. Although the meaning of Melesina itself is unknown, the root name Millicent derives from the Gothic *Amalaswinþa, composed of the elements amals meaning "unceasing, vigorous, brave" and swinþs meaning "strong". The name was borne by Melesina Trench (1768–1827), an Irish writer and socialite known for her poetry and journals, making this the most documented royal or noble use of the name.
