Meaning & Origin
Marlyn is a girl's and boy's baby name of Hebrew origin, a variant of Marilyn, a compound of Mary (from the Hebrew Miryam) and Lynn, meaning 'sea of bitterness' or 'wished-for child' combined with the lake or waterfall element, creating a name of water and grace.
With nearly 6,800 recorded births, Marlyn is a more streamlined spelling of Marilyn — dropping the -i for a cleaner visual form while preserving the name's warm, mid-century American sound. Marilyn Monroe (born Norma Jeane Mortenson) made Marilyn one of the most glamorously associated names of the 20th century. As Marlyn, the name has a gentler, more understated quality than the superstar-associated Marilyn.
