The First Battle of Chuenpi was a naval engagement fought between British and Chinese ships at the entrance of the Humen strait (Bogue), Guangdong province, China, on 3 November 1839 during the First Opium War. The battle began when the British frigates HMS Hyacinth and HMS Volage opened fire on Chinese ships they perceived as being hostile.

The Humen, also Bocca Tigris or Bogue, is a narrow strait in the Pearl River Delta that separates Shiziyang in the north and Lingdingyang in the south near Humen Town in China's Guangdong Province. It is the site of the Pearl River's discharge into the South China Sea. It contains the Port of Humen at Humen Town. The strait is formed by the islands of Chuenpi and Anunghoy on the eastern side, and Taikoktow on the western side. Since 1997, the strait has been traversed by the Humen Pearl River Bridge. Bocca Tigris was the entry to China's only trading city, Canton.
