Tom Weidig

Tom Weidig (born 9 December 1972) is a Luxembourgish politician. He has served as a Member of the Chamber of Deputies from Centre since 2023, as a representative of the right-wing Alternative Democratic Reform Party (ADR).

Weidig was born and brought up in Esch-sur-Alzette. His parents were from Grevenmacher. As a teenager, he represented Luxembourg at the World Junior Chess Championship. He graduated from Imperial College London in 1996 with a Master of Science degree in Theoretical Physics, and earned his doctorate from Durham University in 1999. He was then a postdoc at UMIST, and in 2001 a visiting scholar at Trinity College, Cambridge. He later worked in the finance and venture capital industries. He supports the promotion of the Luxembourgish language.

In February 2025, Weidig received a written warning from his party after he liked a Facebook comment that was described as being anti-LGBTQ+. He issued an apology, but also insisted his actions had been misunderstood.
