Basic Education High School No. 2 Bahan (Burmese: အခြေခံ ပညာ အထက်တန်း ကျောင်း အမှတ် (၂) ဗဟန်း; abbreviated to အ.ထ.က (၂) ဗဟန်း; also abbreviated as BEHS No. 2 Bahan, commonly known as Nanyan) is a public high school in Bahan township, Yangon. Until the nationalization under Ne Win's government occurred in 1963, it was called Nanyang High School (缅甸南洋中学), one of the elite Chinese schools in Myanmar.
The school has a large student body, numbering near 4000. The students are spread across six standards or grades, from Grade 6 (formerly fifth standard) to Grade 11 (formerly tenth standard). A high student-to-teacher ratio exists like most of the schools in Yangon.
