The Socialist Women's Union of Korea (formerly Korean Democratic Women's League, KDWL; or Korean Democratic Women's Union, KDWU) is a mass organization for women in North Korea. It is the oldest and one of the most important mass organizations in the country. The Union has committees on every level of administrative divisions of North Korea, from ri (village) all the way up to provinces.

Membership has been restricted to those women who are not members of any other mass organization. As a result, Union members are effectively composed of women who do not work outside of home. The Union nominally represents these women, but in reality it is used for the implementation of government policies. The Union has had an important role in achieving gender equality and increasing political participation of women in North Korea. In its early days after its foundation in 1945, the Union had well more than a million members, compared to its current membership of 200,000. Its influence has been reduced since the economic reforms of the early 2000s.

The post of the chairperson is usually conferred to the most powerful woman in North Korea. Previous chairpersons include Kim Sung-ae, the wife of the country's former leader Kim Il-sung. The current chair, Pak Sun-hui, is the daughter of Pak Chong-ae, the league's first chairperson.

The Union runs a publishing house that publishes a monthly magazine called Korean Woman ().

The North Korean branch of the Union, the North Korea Democratic Women's League, was established on 18 November 1945 as part of an effort by the North Korea Bureau of the Communist Party of Korea to enroll as many people as possible as members of communist-controlled mass organizations in the northern part of the Korean Peninsula. It was the first mass organization founded with a particular segment of the society in mind. Its initial task was to gather spontaneously formed regional women's' organizations under its control. The Union held its first congress on 10 May 1946. At that time, it had 800,000 members in branches in 12 cities, 89 counties, and 616 townships. By the end of 1946, almost one in five women of the country were Union members as membership had rose to 1,030,000.
