Mahira Hafeez Khan (pronounced [maɦiːraː hafiːz kʰan]; born 21 December 1984) is a Pakistani actress known for her work in films and television. One of the highest-paid actresses in Pakistan, she has received several accolades, including seven Lux Style Awards and eight Hum Awards.

After working as a video jockey for various television shows, Khan made her acting debut in 2011 with a supporting role in Shoaib Mansoor's blockbuster social drama Bol (2011). She then played a troubled wife in the highly successful romantic television drama Humsafar (2011), which won her the Lux Style Award for Best Television Actress. She gained wider recognition for portraying a range of unconventional characters in several top-rated television series, including the religious drama Shehr-e-Zaat (2012), the biographical romance Sadqay Tumhare (2014), and the romantic drama Bin Roye (2016), all of which earned her multiple Best Actress awards and nominations.

Khan established herself by starring as the female lead in two of Pakistan's highest-grossing productions—the 2015 romantic drama Bin Roye and the 2016 coming-of-age musical drama Ho Mann Jahan. Her first project in Hindi cinema came with the crime thriller Raees (2017), which ranks among the highest-grossing Indian films of 2017. She received critical acclaim for her portrayal of a rape victim in the revenge drama Verna (2017), and an aspiring actress in the musical drama Superstar (2019).

She produced the sports-based web series Baarwan Khiladi (2022).

Outside of acting, Khan supports social causes related to women's rights and the refugee crisis. She has worked with UNICEF since 2019 and was appointed as the national and global UNICEF Goodwill Ambassador for Afghan refugees in Pakistan the same year. She has also co-hosted several award ceremonies and is a prominent celebrity endorser for major brands and products. Khan is known to be private about her personal life, which often attracts media attention.

Mahira Khan was born on 21 December 1984 into a Muhajir family in Karachi, Sindh, Pakistan. In an online interview with Reham Khan, she said that her parents are Urdu-speaking Pathans. Her father, Hafeez Khan, was born in Delhi during the British Raj and migrated to Pakistan after the partition of India. She has a younger brother, Hissan Khan, who is a journalist and entrepreneur.

She received her early education at Foundation Public School, where she completed her A-Levels. At the age of seventeen, she moved to California in the United States for higher education and enrolled at Santa Monica College. Mahira was the first woman in her family to travel abroad alone. She later said that living in the United States on her own helped her become "strong and independent." She then enrolled at the University of Southern California for a master's degree in English literature. During this period, she worked part-time as a cashier at Rite Aid. Reflecting on the experience, she said: "I used to mop floors, clean floors, run the till and shut the store at night." After completing her first year, Khan decided to pursue her interest in acting and left her studies, returning to Pakistan.

Khan began her career in 2006 as a video jockey at MTV Pakistan, where she hosted the live show Most Wanted five days a week. She later hosted Weekend with Mahira on AAG TV in 2008, which featured interviews with celebrities.

In 2011, she made her film debut with a supporting role in Bol, directed by Shoaib Mansoor. She played Ayesha, a friend of the lead character, and the film became one of Pakistan's highest-grossing films at the time. The success of the film marked her transition from television presenter to actor.
