Marnix Leonard Alexander van Rij (in Dutch; Flemish ˈmɑrnɪks fɑn ˈrɛi/; born 25 October 1960) is a Dutch politician.
Van Rij grew up in Wassenaar, and he started his career in 1983 as a tax assistant at a tax firm. In addition, he became a member of the Wassenaar Municipal Council in 1986. He moved to professional services firm Ernst & Young (EY) in 1994, and he became a partner in January 1998. He was party chair of the Christian Democratic Appeal (CDA) from 1999 until 2001.[1] He also served as a Senator, a part-time position in the Netherlands, from 2015 to 2019. As a senator, his portfolio consisted of tax affairs, among other themes. On 15 February 2020, Van Rij was appointed as the Island Governor of Sint-Eustatius, and he left EY.[2] After this, Van Rij was interim party chairman of the CDA from 3 April until 11 December 2021.
On 10 January 2022, Van Rij became State Secretary for Finance in the fourth Rutte cabinet. In an interview with newspaper Trouw, Van Rij told that he had declined to succeed Ronald Plasterk as informateur during the 2023–2024 cabinet formation, partly due to the CDA not being part of the talks. He also said he had been one of three candidates to serve as prime minister in the resulting cabinet after Plasterk had withdrawn, but Van Rij pulled out after his first interview. Dick Schoof was eventually chosen.[3] Van Rij's term as state secretary ended on 2 July 2024, when the Schoof cabinet was sworn in.[4]
He has been nominated to serve as deputy Executive Director of the Dutch-Belgian constituency at the International Monetary Fund (IMF) in Washington, D.C. starting on 1 November 2024.[1]
Van Rij is in his second marriage with his American-born wife Courtney. The couple kept their house on Sint Eustatius after moving back to the Dutch mainland.[5] Van Rij has six children.[3]
