The Ba Làng An Peninsula (Vietnamese: mũi Ba Làng An, literally "land nose of Three Villages called An") is a peninsula in Vietnam. Ba Làng An is located in Quảng Ngãi Province, northeast of Quảng Ngãi and 32 km south of Chu Lai. The name was often mispronounced as "Ba Tang An" and known as Batangan during the Vietnam War, although Far Eastern Economic Review and other sources continued to refer to the "Ba Lang An peninsula."
