50Plus (Dutch pronunciation: [ˈvɛiftəx plʏs]; stylised as 50PLUS and abbreviated 50+) is a political party in the Netherlands that advocates pensioners' interests with a centrist political line. The party was founded in 2009 by Maurice Koopman, Alexander Münninghoff and Jan Nagel.

The party first participated in the 2011 provincial elections, in which it won 9 provincial council seats, allowing it to be represented in the Senate by Nagel. Under lead candidate Henk Krol, the party entered the House of Representatives for the first time at the 2012 general election. On 6 May 2021, party leader Liane den Haan, its sole member in the House of Representatives, left to sit as an Independent following an internal dispute. The party re-entered the parliament under the leadership of Jan Struijs after the 2025 general election.
