Mohsin Hamid (Urdu: محسن حامد; born 23 July 1971) is a British Pakistani novelist, writer and brand consultant. His novels are Moth Smoke (2000), The Reluctant Fundamentalist (2007), How to Get Filthy Rich in Rising Asia (2013), Exit West (2017), and The Last White Man (2022).

Born to a family of Punjabi and Kashmiri descent, Hamid spent part of his childhood in the United States, where he stayed from the age of 3 to 9 while his father, now a university professor, was enrolled in a PhD program at Stanford University. He then moved with his family back to Lahore, Pakistan, and attended the Lahore American School.

At the age of 18, Hamid returned to the United States to continue his education. He graduated summa cum laude with an A.B. from the Princeton School of Public and International Affairs in 1993 after completing a 127-page senior thesis, titled "Sustainable Power: Integrated Resource Planning in Pakistan", under the supervision of Robert H. Williams. While he was a student at Princeton, Hamid studied under Joyce Carol Oates and Toni Morrison. Hamid wrote the first draft of his first novel for a fiction workshop taught by Morrison. He returned to Pakistan after college to continue working on it.

Hamid then attended Harvard Law School, graduating in 1997. Finding corporate law boring, he repaid his student loans by working for several years as a management consultant at McKinsey & Company in New York City. He was allowed to take three months off each year to write, and he used this time to complete his first novel Moth Smoke.

Hamid moved to London in the summer of 2001, initially intending to stay only one year. Although he frequently returned to Pakistan to write, he continued to live in London for eight years, becoming a dual citizen of the United Kingdom in 2006. In 2004 he joined the brand consultancy Wolff Olins, working only three days a week so as to retain time to write. He later served as managing director of Wolff Olins' London office, and in 2015 was appointed the firm's first-ever Chief Storytelling Officer.

Hamid's first novel, Moth Smoke, tells the story of a marijuana-smoking ex-banker in post-nuclear-test Lahore who falls in love with his best friend's wife and becomes a heroin addict. It was published in 2000, and quickly became a cult hit in Pakistan and India. It was also a finalist for the PEN/Hemingway Award given to the best first novel in the US. It was adapted for television in Pakistan and as an operetta in Italy.

Moth Smoke had an innovative structure, using multiple voices, second-person trial scenes, and essays on such topics as the role of air-conditioning in the lives of its main characters. Pioneering a hip, contemporary approach to English language South Asian fiction, it was considered by some critics to be "the most interesting novel that came out of [its] generation of subcontinent (English) writing." In the New York Review of Books, Anita Desai noted:

One could not really continue to write, or read about, the slow seasonal changes, the rural backwaters, gossipy courtyards, and traditional families in a world taken over by gun-running, drug-trafficking, large-scale industrialism, commercial entrepreneurship, tourism, new money, nightclubs, boutiques... Where was the Huxley, the Orwell, the Scott Fitzgerald, or even the Tom Wolfe, Jay McInerney, or Brett Easton Ellis to record this new world? Mohsin Hamid's novel Moth Smoke, set in Lahore, is one of the first pictures we have of that world.
