Arab Ahmet is a Neighbourhood, Quarter, Mahalla or Parish of Nicosia, Cyprus and the mosque situated therein. Both the Quarter and the mosque are named after Arab Ahmet Pasha, one of the Turkish commanders in the Ottoman conquest of Nicosia. It is spelled Arabahmet in Turkish and Άραπ Άχμετ in Greek.
At the last Census (2011) it had a population of 3,550. It covers the historic Arab Ahmet neighbourhood in the west of Nicosia within the walls, plus an area west of that outside the walls up to the municipal boundary
The population in 1946 was 2,617 Together with the neighbouring Karamanzade Neighbourhood, it was part of the predominantly Armenian area of Nicosia.
The Neighbourhood outside the walls, is now delimited by the Dept. of Lands and Surveys as follows: The boundary line passes from the point of the Quirini or Cephane (Jeb Khane) bastion to the roundabout just north of the bastion. Namely, the roundabout at the corner of the former site of the Turkish Cemetery, now the site of the Turkish Embassy in Cyprus. From there the boundary continues along Bedrettin Demirel Avenue (Hilarion Avenue) for about a mile to the old municipal boundary. The boundary is then coterminous with the municipal border in a south-westerly direction until the vicinity of the Central Prison. From here the boundary passes south of the prison due east, via Norman St., thence along Dereboyu Avenue and Markos Drakos Ave. until the point of the Roccas bastion. This area includes the Ledra Palace Hotel, British High Commission, Central Prison and the Turkish Cypriot Assembly of the Republic. Parts of the neighborhood outside the walls in the north have been detached from the Arab Ahmet neighbourhood and are now considered parts of Köşklüçiftlik.
