He is the recipient of numerous accolades including four National Film Awards, four Filmfare Awards, and two Asia Pacific Screen Awards. In 2019, he was awarded the Padma Shri.

Born in a small village in Bihar, Bajpayee aspired to become an actor since childhood. He relocated to Delhi at the age of seventeen, and applied for the National School of Drama, only to be rejected four times. He continued to do theatre while studying in college. Bajpayee made his feature film debut with minor roles in Drohkaal (1994) and Bandit Queen (both 1994). He had his breakthrough playing a gangster in Ram Gopal Varma's 1998 crime drama Satya, for which he won the National Film Award for Best Supporting Actor and Filmfare Critics Award for Best Actor. He then acted in films such as Kaun? (1999) and Shool (1999). For the latter, he won his second Filmfare Critics Award for Best Actor.

Bajpayee was born in a Hindu Brahmin family on 23 April 1969 in a small village called Belwa near the city Bettiah in West Champaran, Bihar. He is the second child among his five other siblings, and was named after actor Manoj Kumar. One of his younger sisters Poonam Dubey, is a fashion designer in the film industry. His father was a farmer and his mother was a housewife. As a son of a farmer, Bajpayee would do farming during their vacation. Since childhood, he wanted to become an actor.

His father struggled to gather funds for their education. He studied in a "hut school" till fourth standard, and later did his schooling at Khrist Raja High School, Bettiah. He completed his 12th class from Maharani Janaki Kunwar College in Bettiah.

He moved to New Delhi at the age of seventeen and went to Satyawati, then to Ramjas College, Delhi University. Bajpayee had heard about the National School of Drama from actors such as Om Puri and Naseeruddin Shah, so he applied. He was rejected three times and wanted to commit suicide afterward. He then attended director and acting coach Barry John's workshop after actor Raghubir Yadav's suggestion. Impressed by Bajpayee's acting, John hired him to assist him in his teaching. After that he applied at the National School of Drama for the fourth time, and they offered him a teaching position at the school instead.

Bajpayee is a method actor and a director's actor, and is known for his unconventional roles in films. Actor Nawazuddin Siddiqui has cited Bajpayee's performance in Aks as the inspiration for his role as the antagonist in Kick (2014). Bajpayee has also been vocal about the disparity in the pay he commands, in comparison to the top actors in the film industry. He has cited Amitabh Bachchan, Naseeruddin Shah and Raghubir Yadav as his inspirations.

Director Ram Gopal Varma considers him to be "an education" for himself and said he is "simply the best actor I've ever worked with." Shekhar Kapur, who directed him in Bandit Queen, recalls: "Manoj had the ability to portray a lot just by doing little. He never tried to overplay a scene and seemed totally comfortable with a minimalist statement." According to director Hansal Mehta, Manoj "has the ability to transform himself like few others."
