Dimple Kapadia (born 8 June 1957) is an Indian actress predominantly appearing in Hindi films. Born and raised in Mumbai by wealthy parents, she aspired to become an actress from a young age and received her first opportunity through her father's efforts to launch her in the film industry. She was discovered at age 14 by the filmmaker Raj Kapoor, who cast her in the title role of his teen romance Bobby (1973), which opened to major commercial success and gained her wide public recognition. Shortly before the film's release in 1973, she married the actor Rajesh Khanna and quit acting. Kapadia returned to films in 1984, two years after her separation from Khanna. Her comeback film Saagar, which was released a year later, revived her career. Both Bobby and Saagar won her Filmfare Awards for Best Actress. Through her work over the next decade, she established herself as one of Hindi cinema's leading actresses.

While her initial roles often relied on her perceived beauty and sex appeal, Kapadia was keen to challenge herself and expand her range. She was among the first actresses who starred in women-centred Hindi action films but found greater favour with critics when she took on more dramatic roles in both mainstream and neorealist parallel cinema. Appearing in films ranging from marital dramas to literary adaptations, she played troubled women sometimes deemed reflective of her personal experience, and received acclaim for her performances in Kaash (1987), Drishti (1990), Lekin... (1991), and Rudaali (1993). For her role as a professional mourner in Rudaali, she won the National Film Award for Best Actress and a Filmfare Critics Award. Kapadia followed with character roles in Gardish (1993) and Krantiveer (1994), the latter securing her a fourth Filmfare Award.

Starting in the mid 1990s, Kapadia became more selective about her work, and her screen appearances in the following decades were fewer. She was noted for her portrayal of middle-aged, complicated women courted by younger men in Dil Chahta Hai (2001) and the American production Leela (2002). Her later credits include leading roles in Hum Kaun Hai? (2004), Pyaar Mein Twist (2005), Phir Kabhi (2008), Tum Milo Toh Sahi (2010) and What the Fish (2013), but she attained more success with character roles in Being Cyrus (2006), Luck by Chance (2009), Dabangg (2010), Cocktail (2012) and Finding Fanny (2014). Some of these roles were cited in the media as a departure from the regular portrayals of women of her age in Hindi films. Roles in the Hollywood thriller Tenet (2020) and action film Pathaan (2023) brought her further recognition. Kapadia is the mother of Twinkle Khanna and Rinke Khanna, both of whom are former actresses.
