Vivek Hallegere Murthy (born July 10, 1977) is an American physician and a former vice admiral in the United States Public Health Service Commissioned Corps, who served as the 19th and 21st surgeon general of the United States from 2015 to 2017 and again from 2021 to 2025, under Presidents Barack Obama, Donald Trump, and Joe Biden. Murthy is the first surgeon general of Indian descent, and during his first term as surgeon general was the youngest active duty flag officer in federal uniformed service.

Murthy co-chaired President-elect Biden's COVID-19 Advisory Board from November 2020 to January 2021, alongside former Food and Drug Administration commissioner David A. Kessler and Yale public health professor Marcella Nunez-Smith. On December 7, Biden announced Murthy would return to the role of U.S. surgeon general. The United States Senate confirmed Murthy to the role on March 23, 2021, by a vote of 57–43. In October 2022, Biden nominated Murthy to be the U.S. representative on the World Health Organization's executive board.

Murthy was born in Huddersfield, Yorkshire, England. His parents Hallegere Narayana Lakshminarasimha Murthy and Myetraie Murthy were Iyengars from Karnataka, India, with his grandfather H. C. Narayana Murthy being a director of the Mysore Sugar Company. In 1978, the family moved to Newfoundland, Canada, where his father worked as a district medical officer. When he was three years old, the family relocated to Miami, and his parents established their medical practice.

Murthy was raised and completed his early education in Miami, graduating as valedictorian from Miami Palmetto Senior High School in 1994. He then attended college at Harvard University and graduated magna cum laude in 1997 with a Bachelor of Arts in biochemical sciences. In 2003, Murthy earned an M.D. from Yale School of Medicine and an M.B.A. from Yale School of Management, where he received a Soros Fellowship for New Americans.

During his time at Yale, Murthy helped start "The Healer's Art" – a four-week long elective in which medical students discuss critical topics such as what it means to serve as a healer, how to cope with losing a patient, and how to prevent physician burnout.

While a Harvard freshman in 1995, Murthy co-founded VISIONS Worldwide, which he led for eight years. This nonprofit organization promotes HIV/AIDS education in the U.S. and India. He also co-founded Harvard's bhajan club. In 1997, he co-founded the Swasthya Community Health Partnership to train women as community health workers and educators in rural India.

Murthy completed his internal medicine residency at Brigham and Women's Hospital and Harvard Medical School. As an attending physician at Brigham and Women's Hospital, Murthy cared for thousands of patients while assisting in the education of hundreds of undergraduates, medical students, and residents.

In 2008, Murthy founded and served as president of Doctors for America, a group of more than 15,000 physicians and medical students supporting high-quality affordable care for all.
