This is a list of incidents in Niger that are considered terrorism.

Niger became one of the main allies of the United States in the African theater of the war on terror. It joined the Pan Sahel Initiative in 2003 and the Trans-Saharan Counterterrorism Initiative in 2007.^[1]

Islamist terrorism is common in Niger, but it has historically targeted the government and Westerners instead of Nigerien civilians. The number of incidents spiked multiple times in the 1990s and late 2000s. A significant increase took place in 2014 and 2015, with over 40 incidents taking place in 2015.^[1] In June 2013, between 5,000 and 10,000 refugees arrived in Bosso, fleeing and fighting between Boko Haram and the Nigerian Armed Forces in Borno State of Nigeria. Most blamed the military for the excessive violence and human rights violations.^[2] The border town of Diffa is separated from Nigeria by the Komadougou Yobe river, a recent drop in the river's water level granted large groups of Nigerian refugees the opportunity to flee rebel controlled areas into the yet unaffected Niger.^[3] On 5 February 2015, a Nigerien parliament spokesman announced that discussions will be held regarding Niger's participation in the anti Boko Haram military operations.^[3]

In July 2023, disgruntled officers overthrew Nigerien president Mohamed Bazoum in a coup, claiming that Bazoum's government was not effectively countering the insurgencies of the Islamic State in the Greater Sahara and Jama'at Nasr al-Islam wal-Muslimin in the western part of the country. JNIM and ISGS are most active in the tri-border area between Niger, Mali, and Burkina Faso, the latter two having had coups that installed military juntas within the past two years.^[4] Since the coup, jihadist attacks escalated, with an attack in Koutougou in August 2023 killing 17 soldiers and an attack in Tabatol killing at least sixty Nigerien soldiers.^[5]
