Mortimer is Norman French in Origin.

Mortimer derives from the Norman French toponym Mortemer, built from Old French mort "dead" and mer/meer "mere, pond," denoting a "still or stagnant pool." Carried to England after 1066 as a surname of a powerful Marcher dynasty, it later migrated into given-name use among the gentry. Figures such as Roger Mortimer, 1st Earl of March, and Edmund Mortimer in Shakespeare’s Henry IV embedded the name in English historical memory. It enjoyed modest Victorian popularity and occasional use in the early 20th century, now ranking as a rare, antique choice.

Variants and shortenings include Mort, Morty/Mortie, and the French surname form Mortemer; Mortimera appears sporadically as a feminization. The name’s meaning evokes quiet waters and a stately, old-world tone. Cultural references range from Marlowe’s Edward II to characters like Mortimer Brewster (Arsenic and Old Lace) and Disney’s Mortimer Mouse.
