Meaning: oath of God

Ilse is a German and Dutch girl’s name, meaning “oath of God.” It is a diminutive of the Hebrew name Elisabeth and a possible variant of Elsa. From Elsa of Arendelle in Frozen to Spanish model and actress Elsa Pataky, Ilse’s counterpart has definitely grown in popularity in recent years. If you love Elsa but are looking for something a little more rare, the name Ilse is a charming alternative.
