Abi is a Biblical name meaning "my father" and can refer to God. Abi is the name given in 2 Kings 18:2 to the mother of Hezekiah, king of Judah. The name translates as "my father," and is probably a shortened version of the name. The parallel verse in 2 Chronicles 29:1 gives this name as Abijah (NRSV, other versions use Abiah or Abia), which means "Yah is my father."
