Martine Deprez (born 26 April 1969 in Wiltz) is a Luxembourgish politician who serves as Minister of Health and Social Security in the Frieden-Bettel government since 17 November 2023.

[8] As the term of Council of State president Georges Schroeder came to an end on 12 June 2012, a new member was needed and Deprez was proposed.

During coalition talks, newly elected DP member of parliament and virologist Gérard Schockmel had proposed himself for Minister of Health, which added further surprise to Deprez' nomination.

[3][19] In an interview with Radio 100,7 on 28 November 2023, Deprez gave a first insight into her views on the overhaul of the Luxembourgish pension system.

She stated needs for consultations with the civil society if prognoses showed that the pension system would turn out to be in an imbalance in a few years.

[19][21] Trade union leaders condemned these announcements, criticizing Deprez for talking with the press about her plans before bringing them up with the social partners and for wanting to "privatize" the pension system.

[26] Although she was aware of the risks of nicotine pouches and emphasised that they could tempt young people to start smoking, she was not in favour of a ban.

[27] After their petition reached the necessary quorum, a group of activists demanded a ban on so-called "virginity certificates" in a public hearing in the Chamber of Deputies on 18 April 2024.

[28] Between 2008 and 2012, Deprez was Secretary General of the Union Grand-Duc Adolphe (UGDA), an umbrella organization for music interests in Luxembourg.

After an internal dispute over the management styles, Deprez became interim president of the UGDA after an extraordinary congress on 29 October 2015.
