Central Provost of Islamic Republic of Iran Army (Persian: دژبان مرکز ارتش جمهوری اسلامی ایران; Dežbān Markaz), acronymed DEJAJA (Persian: دژاجا), is the provost and military police with an authority within all military branches of Islamic Republic of Iran Army (Artesh).

The provost is a subdivision to the military's Joint Staff and has seniority over designated provosts —like the "Sea Police" (Persian: پلیس دریائی) of Navy and the "Air Police" (Persian: پلیس هوائی) in the Air Force.

The provost is also responsible for performing ceremonial duties; it has honor guard units, including the "Presidential Ceremony Guard" (Persian: گارد تشریفات ریاست جمهوری), which maneuvers during official trips of the President of Iran and during visits by heads of state.

At the same time, this unit is responsible for the protection of places such as Saad Abad Palace and Museum and the establishment of order and security in Tehran's Behesht-e Zahra.
