The PL-2 (Chinese: 霹雳-2; pinyin: Pī Lì-2; lit. 'Thunderbolt-2') is an infrared homing (IRH) air-to-air missiles (AAM) developed in the People's Republic of China (PRC). It was a reverse-engineered Soviet Vympel K-13, which in turn was a reverse-engineered American AIM-9B Sidewinder.

The PL-2 was the root of a family of AAMs; of the derivatives, only the PL-5B was successful.

The PRC acquired an intact AIM-9B during the Second Taiwan Strait Crisis in 1958. Air combat between over the strait between the Republic of China Air Force (ROCAF) and the People's Liberation Army Air Force (PLAAF) marked the combat debut of AAMs, with Sidewinder-armed ROCAF F-86 Sabres achieving notable success against PLAAF J-5s. On 28 September, a J-5 returned to base with an unexploded Sidewinder lodged in its airframe.

The PRC's attempts to reverse engineer the AIM-9B failed. The PRC transferred the missile to the Soviet Union, which agreed to share the reverse engineered product; in 1961, the PRC received technical data for and examples of the K-13. Replication of the K-13 began in 1962 with live-fire tests occurring in 1967. In 1967, Factory 331 in Zhuzhou was permitted to begin series production, but series production was delayed until 1970 due to the Cultural Revolution. In 1970, production transferred to the Nanfeng Machinery Plant in Hanzhong. Production of the PL-2A ended in February 1984.
