Pieter Herman Omtzigt ([ˈpitər ˈɦɛrmɑn ˈɔmtsɪxt]; born 8 January 1974) is a Dutch former politician who served as a member of the House of Representatives between 2003 and 2025 apart from a short interruption between June and October 2010. He was a member of the Christian Democratic Appeal (CDA), but left in 2021 and continued as an independent. In August 2023, he founded a new party called New Social Contract, its name taken from his 2021 manifesto. Three months later, his party won 20 out of 150 seats in the 2023 Dutch general election. On 18 April 2025, he announced that he would leave politics due to his burnout.
In his political work, Omtzigt focused on matters of taxes and pensions. He rose to prominence for his role in bringing attention to the childcare benefits scandal.
