Ping Hai (Chinese: 平海; literally: "Amicable Seas") was a light cruiser in the Chinese fleet before World War II and the second ship of the Ning Hai class. The ship was laid down in China to the specifications supplied by the Japanese, and Japanese advisors were hired to oversee the construction. Compared to its sister ship Ning Hai, it had a lower-output powerplant and lacked seaplane facilities. Its anti-aircraft armament was also different from that of its sister.
