Nicușor Dan

Nicușor Daniel Dan (born 20 December 1969) is a Romanian mathematician and politician serving as the seventh President of Romania since 2025. He previously served as the Mayor of Bucharest from 2020 to 2025 and as a member of the Chamber of Deputies from 2016 to 2020.

Born in Făgăraș, Brașov County, Dan studied mathematics at the University of Bucharest before continuing his studies in France, where he obtained a Master's degree from the École normale supérieure and a PhD from Paris 13 University. After returning to Romania, he founded the Școala Normală Superioară București, a research institution in mathematics, and participated in civic initiatives concerning urban governance and heritage preservation.

In 2015, Dan founded the Save Bucharest Union (USB), a political party focused on anti-corruption and urban development. He co-founded the Save Romania Union (USR) in 2016 and resigned in 2017 following internal disagreements regarding the party's ideological direction, subsequently advocating a big tent approach centred on institutional reform. He served in the Chamber of Deputies from 2016 until he was elected mayor of Bucharest in 2020. He was re-elected in 2024 and served until he was elected president. As mayor, his administration oversaw public infrastructure projects, municipal financial policy, and administrative reforms.

Dan was elected President of Romania in 2025 as an independent candidate, with second-round support from the USR, the National Liberal Party (PNL), and the Democratic Union of Hungarians (UDMR), defeating George Simion of the Alliance for the Union of Romanians (AUR). He campaigned on a pro-European Union and pro-NATO platform. His presidency has been marked by political instability, including the collapse of a governing coalition led by Prime Minister Ilie Bolojan, president of the PNL, following a motion of no confidence in May 2026.

In 2026, some commentators described his contacts with the Social Democratic Party (PSD) leaders and figures within the American Republican Party as a political realignment towards euroscepticism, a characterisation he disputed while reaffirming Romania's commitments to the EU and NATO.
