The Hanover stabbing that occurred on 26 February 2016 was a terrorist stabbing of a police officer in Hanover, Germany, by a 15-year-old girl born to a Moroccan mother and a German father. She had been raised under the influence of salafist preachings, as early as 7 years. She had been investigated by the Federal Office for the Protection of the Constitution for preparing a serious crime already in 2014 and had traveled to meet ISIS members in Istanbul in November 2015. It was the first reported attack by an ISIS sympathiser in Germany.

On 26 February 2016, two police officers approached a 15-year-old and asked for her identification papers. The girl stabbed a police officer in the back of the neck at Hanover Central Station, causing severe injuries. The officer survived after surgery. After her arrest, police found a second and larger knife. This was the first reported lone-wolf terrorist attack by a sympathizer of the Islamic State in Germany.

The 15-year-old perpetrator was born in Hanover to a Moroccan mother and a German father who converted to Islam. At age 7, she appeared in a video reciting the Quran with the German Salafist preacher Pierre Vogel.
In 2014, the Federal Office for the Protection of the Constitution, Germany's domestic intelligence agency, started investigating the girl for preparing a serious crime in 2014; 
NDR television reported that the day after the November 2015 Paris attacks she described it as the "happiest day of my life", adding: "Allah bless our lions".According to a Deutsche Welle report, a family member called authorities expressing concerns over radicalisation, and police met with the family days later.
In November 2015, the perpetrator traveled to Istanbul where she met members of ISIL, who planned to help her with entry into Syria. In January 2016 she returned to Germany. In January 2017, it was reported in court that orders to carry out a "martyrdom attack" in Germany were given.
