National Thowheeth Jama'ath was a Sri Lankan Islamist jihadist militant group implicated in the 2019 Sri Lanka Easter bombings. It is believed to have ties to the Islamic State (IS). President of Sri Lanka Maithripala Sirisena banned National Thowheed Jamath on 27 April 2019 and designated it as a terrorist organisation along with Jammiyathul Millathu Ibrahim.
