This is a timeline of incidents in 2010 that have been labelled, or investigated as possible cases of "terrorism" and are not believed to have been carried out by a government or its forces (see state terrorism and state-sponsored terrorism). Over 1,375 people died from terrorist incidents this year.
Casualties figures in this list are the total casualties of the incident including immediate casualties and later casualties (such as people who succumbed to their wounds long after the attacks occurred).
Casualties listed are the victims. Perpetrator casualties are listed separately (e.g. x (+y) indicate that x victims and y perpetrators were killed/injured).
Casualty totals may be underestimated or unavailable due to a lack of information. A figure with a plus (+) sign indicates that at least that many people have died (e.g. 10+ indicates that at least 10 people have died) – the actual toll could be considerably higher.
If casualty figures are 20 or more, they will be shown in bold. In addition, figures for casualties more than 50 will also be underlined.
