Iseah is a unique, unisex given name of Hebrew origin, meaning "God is salvation". It is often spelled alternatively as Isiah or Isaiyah, but its pronunciation maintains the same phonetic value. Iseah was rarely used in past centuries, yet it has gained some popularity in recent times, particularly among parents seeking distinctive names for their children. This name is likely to attract attention due to its unique spelling and pronunciation, setting it apart from more common names. It does not have any specific associated saint's day or feast day, as it is not derived from a saint's name but rather from the Hebrew Bible.
The name Iseah experienced varying popularity over the years with a significant spike in usage between 2003 and 2007, followed by a decline from 2008 onwards.
