Dianbai District, alternately romanized as Tinpak,[a] is an urban district of the prefecture-level city of Maoming in southwestern Guangdong Province, China.

Dianbei Commandery was established in AD 528 under the Liang dynasty.

It and the subsequent Dianbei County were organized under Gaozhou Commandery.

After the Chinese Civil War, it was placed under Maoming and eventually promoted to an urban district.

Dianbai absorbed Maoming's former Maogang District on 23 February 2014.
