Meaning & Origin
A unisex given name from Hebrew, variant of Micah.
Mica is a unisex baby name of Hebrew origin, a variant of Micah meaning 'who is like God?' — a rhetorical question asserting God's incomparable nature. Micah was a minor prophet in the Old Testament whose book contains the famous verse: 'What does the Lord require of you but to do justice, love kindness, and walk humbly with your God.'
Mica is also the name of a shimmering silicate mineral that forms in glittering sheets — giving the name both spiritual depth and a natural, luminous quality that makes it appealing to parents drawn to nature-inspired names.
