Humza Haroon Yousaf (born 7 April 1985) is a Scottish politician who served as First Minister of Scotland and Leader of the Scottish National Party (SNP) from March 2023 to May 2024. He served under his predecessor Nicola Sturgeon as justice secretary from 2018 to 2021 and then as health secretary from 2021 to 2023. He has been Member of the Scottish Parliament (MSP) for Glasgow Pollok since 2016, having previously been a regional MSP for Glasgow from 2011 to 2016.

Born to Pakistani immigrants in Glasgow, Yousaf studied politics at the University of Glasgow, before working as a parliamentary assistant for Bashir Ahmad, the first Muslim and the first second-generation immigrant elected to the Scottish Parliament. Following Ahmad's death in 2009, Yousaf went on to work as a parliamentary assistant for both Alex Salmond and Sturgeon. Prior to his election at the 2011 Scottish Parliament election, he worked in the SNP's party headquarters as a communications officer. Appointed as a junior minister under Salmond in 2012, Yousaf served as Minister for External Affairs and International Development until 2014.

Yousaf supported Sturgeon's successful leadership bid in 2014 and after she was sworn in as first minister, he was subsequently appointed as Europe minister before being appointed Minister for Transport and the Islands in 2016. As part of a cabinet reshuffle of Sturgeon's second ministry in 2018, Yousaf was promoted to the cabinet as justice secretary. He introduced a controversial hate-speech bill to parliament which ultimately became law as the Hate Crime and Public Order (Scotland) Act 2021. In 2021, he was appointed health secretary during the later phase of the COVID-19 pandemic and was responsible for the NHS's recovery, as well as the mass roll-out of the vaccination programme which began under his predecessor.

Following Sturgeon's resignation as leader of the SNP and as first minister, Yousaf won the 2023 SNP leadership election. Yousaf was appointed first minister on 29 March 2023, becoming the youngest person, the first Scottish Asian, and the first Muslim to serve in office. He was sworn into the Privy Council in May 2023. In April 2024, he formed a minority government after terminating a power-sharing agreement with the Scottish Greens. After facing an imminent motion of no confidence amid a government crisis, he announced his intention to resign as first minister and party leader on 29 April 2024. He formally resigned on 7 May 2024 and was succeeded by John Swinney, becoming the second-shortest-serving first minister, after Henry McLeish.

Humza Yousaf was born on 7 April 1985 in Rutherglen Maternity Hospital in Rutherglen, South Lanarkshire. He is a son of first-generation Muslim Rajput of Pakistani immigrants: his father Mian Muzaffar Yousaf was born in Mian Channu, Punjab, Pakistan, and emigrated from the city with his family in the 1960s, eventually working as an accountant. His paternal grandfather worked in the Singer sewing machine factory in Clydebank in the 1960s. Yousaf's mother, Shaaista Bhutta, was born in Nairobi, Kenya, to a family of Pakistani-Punjabi descent. Due to their non-African background, her family was regularly harassed and occasionally assaulted: following an incident where her mother was attacked with an axe, they emigrated to Scotland.

Humza attended Mearns Primary School in Newton Mearns, East Renfrewshire. Yousaf was one of two ethnic-minority pupils to attend his primary school. Yousaf was privately educated at Hutchesons' Grammar School, an independent school in Glasgow, where his Modern Studies lessons inspired him to become involved in politics.

He described the September 11 attacks as the "day that changed the world and for me" when he was 16 years old. Prior to the attack, Yousaf was close to two pupils whom he sat next to in his registration class, but after the attack in New York, he claims that they asked him questions such as, "Why do Muslims hate America?"

Yousaf studied politics at the University of Glasgow where he was President of the Glasgow University Muslim Students Association. He graduated in 2007 with a Master of Arts (MA).
