Anand Mohan Singh (born 28 January 1954) is a politician and founder of the now-defunct Bihar People's Party (BPP). He served life imprisonment for instigating killing of Gopalganj district magistrate, G. Krishnaiah in 1994. In April 2023, Government of Bihar amended jail rules for his early release.

Anand Mohan Singh comes from Pachgachhia village in Saharsa district, Bihar. He belongs to Rajput Family. He is the grandson of Ram Bahadur Singh , an Indian freedom fighter. His introduction to politics came through involvement with the Sampoorna Kranti movement of Jayaprakash Narayan, which caused him to drop out of college in 1974.

Singh has had numerous charges filed against him at various times, many of which were either dropped or resulted in acquittal. He and six other people, including his wife Lovely Anand, were accused in relation to the 1994 murder of a Dalit District Magistrate (DM) from Gopalganj, G. Krishnaiah, who was lynched on a major highway near to Muzaffarpur during a funeral cortege for the BPP member and gangster, Chhotan Shukla. In 2007, the Patna High Court sentenced him to death for abetting the crime. The sentence was reduced to rigorous life imprisonment in 2008, when the six other accused were also acquitted due to lack of evidence. The reduction was because there was no evidence that Singh was the actual assailant. In 2012 Singh failed in his appeal to the Supreme Court of India against the reduced sentence. The same Supreme Court hearing dismissed an appeal from the Government of Bihar for reinstatement of the death penalty and for an overturning of the acquittal of the six other people.

At the time of the original sentence in 2007, Singh was the first Indian politician since independence to have been given a death penalty. Soon after that sentence, upon being transferred from Patna's Beur jail to that of Bhagalpur, Singh went on hunger strike in protest of the facilities and being split from Akhlaq Ahmed and Arun Kumar, who had received death penalties in the same case. The jail authorities were unsympathetic, noting that rules dictated those sentenced to death should sleep on the floor and be allowed only simple food.

In April 2023, Bihar Chief Minister Nitish Kumar tweaked jail rules for his early release.

Despite being in prison, Singh aided his wife, Lovely Anand, whom he had married in 1991, in standing as an INC candidate in the 2010 Bihar Assembly elections and as a Samajwadi Party candidate in the 2014 general elections. The Supreme Court had barred convicted criminals from standing in elections but he still has much influence. She has claimed that her husband is the victim of a political conspiracy.

People from his home village of Panchgachiya consider him to be a Robin Hood figure and recently Anand Mohan was released from jail in a 30-year-old murder case to attend his son's engagement ceremony, which was attended by leaders of the ruling coalition, including CM Nitish Kumar.[1] Tehelka said in 2007 that

it was his muscleman image that made Mohan’s name synonymous with terror in Bihar’s poverty-ridden Saharsa-Supaul belt for the past 20 years. He and Munna Shukla faced several criminal cases, many of them for murder, in various courts across Bihar. While Shukla still remains a dreaded figure around Muzaffarpur and Vaishali districts in north Bihar, Mohan is notorious in the Saharsa-Supaul belt as a criminal and sometimes as a kind of folk hero.
