Kajol, born Kajol Vishal Devgan on 5 August 1974 in Mumbai, India, stands as one of the most iconic and successful actresses in the history of Hindi cinema, celebrated for her natural acting prowess, expressive eyes, and remarkable versatility. Hailing from a prominent film family, she is the daughter of actress Tanuja and filmmaker Shomu Mukherjee, and her debut came in 1992 with Bekhudi while she was still in school. Though that film did not achieve major commercial success, she chose to leave her studies behind, and her career quickly gained momentum with a series of standout roles. She first captured widespread attention as the female lead opposite Shah Rukh Khan in the 1993 thriller Baazigar, a major hit that showcased her ability to hold her own alongside established stars. The following year, she solidified her rising status with the romantic comedy Yeh Dillagi, which earned her a Filmfare Award for Best Actress.

The mid-1990s marked a transformative period for Kajol, as she became the defining leading lady of the decade through two of the most beloved romantic films in Indian cinema. Her portrayal of Simran in Aditya Chopra's 1995 blockbuster Dilwale Dulhania Le Jayenge became a cultural phenomenon, and the film's enduring popularity cemented her place in film history. Three years later, she delivered another iconic performance in Karan Johar's directorial debut Kuch Kuch Hota Hai, playing the tomboyish Anjali, a role that earned her a second Filmfare Award for Best Actress. Beyond romance, she demonstrated her dramatic range with critically acclaimed turns as a psychopathic killer in the 1997 thriller Gupt: The Hidden Truth and as a woman seeking revenge in the 1998 film Dushman. Her chemistry with Shah Rukh Khan became legendary, and their collaborations defined an era of Hindi cinema.

In 2001, Kajol starred in the family drama Kabhi Khushi Kabhie Gham, a massive hit that won her a third Filmfare Award for Best Actress. Following this, she took a deliberate step back from full-time acting to focus on her personal life, working only sporadically over the next decade. She married actor and filmmaker Ajay Devgn in 1999, and the couple has two children together. Her selective filmography during this period included the romantic thriller Fanaa (2006), which earned her a fourth Filmfare Award for Best Actress, and the socially conscious drama My Name Is Khan (2010), directed by Karan Johar, which brought her a fifth Best Actress award at the ceremony. In 2011, the Government of India honored her with the Padma Shri, the country's fourth-highest civilian award, recognizing her contributions to the arts.

Kajol continued to balance mainstream and unconventional projects in the 2010s and beyond. Her highest-grossing releases include the 2015 comedy Dilwale and the 2020 period epic Tanhaji, both of which co-starred her husband Ajay Devgn. In recent years, she has embraced the digital space, starring in streaming projects such as the critically acclaimed drama Tribhanga (2021), the legal series The Trial (2023), and the mystery thriller Do Patti (2024). Beyond acting, she is a dedicated social activist, particularly known for her work with widows and children, and she serves as a manager at Devgn Entertainment and Software Ltd. She also appeared as a talent judge on the reality show Rock-N-Roll Family in 2008. With seven Filmfare Awards and a legacy of unforgettable performances, Kajol remains a beloved and influential figure in Indian cinema, admired for her authenticity, resilience, and enduring appeal.
