Bij1 (Dutch: [bɛiˈeːn] , lit.'together'), stylised as BIJ1, formerly known as Article 1 (Dutch: Artikel 1), is a political party in the Netherlands. It is described as socialist and is on the left-wing to far-left of the political spectrum. It was founded in Amsterdam in 2016 by Sylvana Simons, a media personality and politician who was formerly briefly connected to another party, Denk. Bij1 saw a breakthrough during the 2018 municipal elections and 2021 Dutch general election in which it won representation in parliament but went through a long period of internal unrest and instability after. Former GroenLinks politician Tofik Dibi has led the party since August 2025.
