Mio is a Japanese female name with a variety of meanings depending on the kanji used:
- “beauty; beautiful + cherry blossom” (美桜);
- “beauty; beautiful + cord, thread” (美緒);
- “beauty; beautiful + center, middle” (美央);
- “waterway; channel” (澪);
Written in hiragana it’s みお.
Mio is also a male name used by Swedish author Astrid Lindgren for her 1954 children’s book Mio, My Son, a fantasy story about a boy who finds out he is the son of a king. I’m not sure whether she based it on the Italian and Spanish word mio meaning “my; mine” which comes from Latin meus derived from Proto-Italic *meos (my). She may also have based it as a male form of Mia, the Scandinavian, Dutch, and German diminutive of Maria which is the Latin form of Mary which ultimately comes from Hebrew female name Miriam, a name of unknown meaning though possible meanings ascribed to it are “sea of bitterness”, “rebelliousness” or “obstinacy”, and “wished for child”. It’s also possible that it might be derived from an Egyptian name either meaning “beloved” from myr, or from mr “love”.
