Alexander De Croo (Dutch: [aːlɛkˈsɑndər də ˈkroː]; born 3 November 1975) is a Belgian politician and businessman who served as Prime Minister of Belgium from 2020 to 2025.

Previously from 2012 to 2020, De Croo serve as deputy prime minister governments of Elio Di Rupo, Charles Michel, and Sophie Wilmès.

De Croo was born in Vilvoorde and studied business engineering at the Vrije Universiteit Brussel before attaining an MBA at Northwestern University in the United States.

He chose Vincent Van Quickenborne and Patricia Ceysens as his running mates to compete against Marino Keulen and Gwendolyn Rutten.

[9][10] Five months after being elected party leader, De Croo threatened to withdraw the Open VLD from the governing coalition if there was no solution to the constitutional dispute in the Brussels-Halle-Vilvoorde voting issue.

[23] In December 2018, De Croo took the stage during the Global Citizen Festival Mandela 100 concert in Johannesburg, South Africa.

[24] Under the caretaker administration of Prime Minister Sophie Wilmès, he oversaw a financial stimulus package to tackle the COVID-19 crisis and a deal to save Brussels Airlines in 2020.

[33] In February 2022, the government adopted a law to make the labour market more flexible: employees have the option, provided that their company agrees, of switching to a four-day week.

[36] In November 2023, De Croo called the Israeli bombing campaign in the Gaza Strip "disproportionate", but said that "Belgium will not take sides" in the Israel–Hamas war.

[38] On 26 February 2024 DeCroo travelled to Paris, where Emmanuel Macron was holding an emergency summit over the situation in Ukraine, as they had just suffered the loss of Avdiivka.

[40][41][42] Following the release of the 2024 Belgian federal election results, De Croo and his party suffered a major electoral defeat.

[43][1] In September 2024, during their welcome addresses for Pope Francis on his visit to the country, De Croo, along with King Philippe, publicly criticised the Catholic Church over sexual abuses committed by clergy in Belgium.

De Croo said he would summon the Belgian apostolic nuncio, Franco Coppola, so as to protest the pope's remarks as an “unacceptable” interference in his country’s domestic affairs.

Like the majority of party leaders in Belgium, De Croo is in favour of greater limits on the political power of the Belgian monarch.

[47] He is a keen equestrian and takes part in a formal event each year together with his father; in 2010 he broke a foot and an elbow when he fell from his horse.
