This is an incomplete list of mass stabbings in Germany. The casualty figures of mass stabbings below include violence-related deaths and injuries with a knife, hatchet and spear respectively, casualty inflicted by legal intervention (i.e., deaths caused by law enforcement and other persons with legal authority to use deadly force acting in the line of duty), as well as suicide.
The list is incomplete, because no federal statistics on all stabbings in Germany are available (unlike for example in the United States, FBI Crime statistics).
The Federal Criminal Police Office started to track solely knife attacks in 2020 and knife attacks are defined as either mere threats with a knife or the actual attacks.
Data from the police crime statistics of individual German states show, that in several states the number of stabbings increased from 2013 to 2018 by over 30%. In 2020 alone, there were at least 100 deaths from nearly 20,000 knife attacks. A large proportion of the crimes are related to domestic violence. The overall number of incidents of intentional simple bodily harm increased by 7.4% from 399,699 in 2022 to 429,157 in 2023. The number of non-German suspects increased more (13%) than the number of German suspects (4%). The highest increase of 20% was in immigrants in Germany, even though they perpetrated only 31.830 out of the 430,000 attacks.
As far as knife attacks are concerned: In 2023, 8,951 cases or 5.8 percent of acts of serious bodily harm (assault) were recorded as "knife attack", a rise in absolute numbers but roughly the same proportion as in 2022 (5.6 percent, altogether 8,160 cases). In 2023, 4,893 cases or 10.9 percent of robberies/theft were knife attacks, an increase in absolute numbers, but an unchanged proportion compared to 2022, with 11.0 percent (4,195 cases).
There is evidence that severe injuries have doubled from 2014 to 2023, per the statistics of the trauma registry of the Deutsche Gesellschaft für Unfallchirurgie (German Association for Trauma Surgery): From 2014 to 2023, 4,917 people with severe knife stab injuries were admitted to German hospitals out of a total of 212,628 admissions to an ICU due to serious injuries. Here, the overall proportion of knife injuries increased sharply from 2014 to 2023, from just under 2 to over 3 %, even though since 2018, patients have to give their written consent in order to be included in the statistics (which caused a high number of unreported cases).
