Serang Regency (Sundanese: {{Sund|ᮞᮨᮛᮀ}}) is a regency of Banten province, Indonesia. It is located in the northwest corner of the island of Java. The administrative center of the regency is at Ciruas, while the capital of the province is the independent municipality of Serang (Kota Serang) which was split off the regency on 17 July 2007.
