Jaysh al-Ummah al-Salafi fi Bayt al-Maqdis, better known as Jaysh al-Ummah, is a Salafi jihadist and Palestinian nationalist militant group in the Gaza Strip that was formed in 2005. Jaysh al-Ummah had only 25 members by 2008, and it aimed for the implementation of sharia law in all Muslim communities and the liberation of Palestine and the al-Aqsa Mosque. Jaysh al-Ummah supported al-Qaeda and opposed ISIL and Hamas, viewing Hamas as too moderate and not focused enough on Islamist projects.
