John Kennedy (born April 17, 1966), better known by his stage name Vikram (Tamil: விக்ரம்), is a National Film Award-winning Tamil film actor. He is also a playback singer and dubbing artist. He made his debut in the 1990 film En Kadhal Kanmani, which was followed by a series of low-budget Tamil, Telugu and Malayalam films throughout the early decade. Following the failure of his early films, Vikram appeared as a dubbing artiste to prominent actors, whilst trying to find a breakthrough in terms of his acting career. After the critical and commercial success of Sethu (1999) he has been part of numerous other commercially successful films and has earned major critical acclaim for many of his performances. During his years in the Indian film industry, he has won three Filmfare Awards, as well as securing India's most prestigious film award, by achieving the National Film Award for Best Actor.

While some of Vikram's best-known films, Dhill (2001), Dhool (2003), Gemini (2002), Saamy (2003), Kanthaswamy (2009) remain some of Tamil cinema's biggest hits, performances in films like Sethu (1999), Kasi (2002), Pithamagan (2003) and Anniyan (2005) have won him critical acclaims and awards, making Vikram one of the most successful actors of Tamil cinema.
