bio dad

Natural male parent

Bio dad is informal for biological dad—one's father by genetics rather than adoption, step-relationship, or other family arrangement.

The term typically appears in contexts where multiple father figures exist and the distinction matters: My bio dad left when I was two, but my stepdad raised me.

Also written biodad.
