The name Jordan was chosen by the residents in honor of St. John the Baptist, their patron saint. According to local folklore, he saved the inhabitants from slaughter during the Moro raid in the Spanish era.
Nueva Valencia was established as a separate municipality in 1941. It was only in July 1995 when San Lorenzo and Sibunag were created, leaving Jordan with only 14 barangays. Before these two towns was created, Jordan was composed of 33 barangays.
