Radikal Ungdom

The Danish Social Liberal Youth (Danish: Radikal Ungdom, literally Radical Youth, abbreviated RU), is a political youth organization in Denmark, built around the ideals of social liberalism. Radical indicates a connection to 19th and 20th century radicalism, a connection shared with the organisation's mother party, the Danish Social Liberal Party.

The current organization was founded on April 30, 1994 under the name Radikal Ungdom of 1994, after the former youth organization Radikal Ungdom was dissolved due to widespread fraud with funding from the Danish Youth Council. The organization bore the name Radikal Ungdom of 1994, until it was changed back to Radikal Ungdom at the organisation's national congress in 2015. The original organisation was founded in Copenhagen in 1904 and merged into a larger national organization founded in 1911.

The Social Liberal Youth of Denmark is a member of three liberal international umbrella organizations: The Nordic Centre Youth (NCF), European Liberal Youth (LYMEC) and the International Federation of Liberal Youth (IFLRY).

At the 2019 party congress, Sigrid Friis Proschowsky stepped down as party president after two years of leadership. She was succeeded by Lukas Lunøe. Caroline Valentiner-Branth and Cornelius Sode were elected as organizational vice-president and political vice-president respectively.
