Operation Pokpoong (폭풍 작전; Korean for Storm) was an offensive operation of the Democratic People's Republic of Korea (DPRK) against the Republic of Korea (ROK) that marked the start of the Korean War. The operation began at 04:00 KST on 25 June 1950 along the 38th parallel north without a declaration of war.

The operation was planned by both the Democratic People's Republic of Korea and the Union of Soviet Socialist Republics (USSR). In addition, the USSR supplied weapons such as tanks and aircraft to its communist ally. With the support from the USSR, the DPRK was able to take control of the ROK capital Seoul within a few days.

The original goal for the operation was to occupy the entire Korean Peninsula by 15 August 1950 ― 50 days, with an average 10 km advance each day ― in commemoration of the 5th anniversary of the Gwangbokjeol. However, heavy losses incurred by the DPRK II Corps, which was in charge of the eastern front, at the hands of the ROK 6th Infantry Division, enabled the ROK to delay the DPRK advance. Soon, the United States joined the war on June 27, and the United Nations Security Council passed Resolution 84 on July 7.
