Pedro Nuno de Oliveira Santos (born 13 April 1977) is a Portuguese economist and politician, who has served as the Secretary-General of the Socialist Party from January 2024 to May 2025. Santos previously held positions in the Portuguese Government under António Costa, first as Secretary of State for Parliamentary Affairs, from November 2015 to February 2019, and afterwards as Minister of Infrastructure and Housing, from February 2019 to December 2022.

Santos has a degree in economics from ISEG-UTL. He was Secretary-General of the Socialist Youth from 2004 to 2008, and a member of the Assembly of the Republic in the 10th and 12th Legislatures. As Secretary of State for Parliamentary Affairs in the XXI Constitutional Government, he was responsible for coordinating the confidence and supply agreement with the Communist Party, the Left Bloc and "The Greens", a government solution that became colloquially known as the geringonça.

In December 2023, Santos was elected to succeed António Costa as Secretary-General of the Socialist Party. He assumed office on 7 January 2024.

Under his leadership, the PS lost both the 2024 and 2025 legislative elections, suffering a steep decline in votes and seats in both, and Santos announced his resignation after the latter.
