General elections were held in the Netherlands from 15 to 17 March 2021 to elect all 150 members of the House of Representatives. The election had originally been scheduled to take place on 17 March. However, due to the COVID-19 pandemic, the government decided to open some polling stations two days in advance to ensure safe voting for elderly and immunocompromised citizens. Citizens aged 70 years or older were also given the opportunity to vote by post. The election was held two days before the 2021 Curaçao general election.
