Eric Joyce has been charged with two counts of common assault after he allegedly attacked a teenage boy in a north London shop.
The Falkirk MP, 54, has denied attacking the boy in Chalk Farm on October 17 this year.
He previously claimed he was trying to detain the teenager after he allegedly vandalised the store, adding that he did not feel he was "in the wrong".
Joyce, a former Army major and ex-Labour MP, has also been charged with one count of criminal damage following the incident, Scotland Yard said today.
He announced he would stand down from Parliament at next year's election.
He is due to appear at Highbury Corner Magistrates' Court on December 30.
Joyce spent 21 years in the armed forces before launching his career as a politician.
He was shortlisted as a Labour candidate for the first Scottish parliament elections in 1999 and became the elected representative for Falkirk in 2000.
Writing on his blog following his arrest in October, Joyce said: "I detained a youth in a shop in London. Damage had been done to the store.
"I asked the shopkeeper to call the police, and when officers arrived they arrested the youth and informed me that drugs had been recovered from the scene.
"The officers also informed me that the youth had immediately made a complaint that I had assaulted him by detaining him. I was questioned by the police and told that because of my identity the Crown Prosecution Service (CPS) and the Metropolitan Police Press Office would be informed of the incident.
"I understand the Metropolitan Police has now made the matter public. I will make no further comment for now, other than to say a) that no alcohol was involved and b) I am not in the habit of summoning the police if I feel that I am in the wrong."
A Met police spokesman said a 14-year-old boy who was arrested for possession of cannabis in connection with the incident was later given a youth reprimand.
