Tirana County (Albanian: Qarku Tiranë), officially the County of Tirana (Albanian: Qarku i Tiranës), is a county in the Central Region of Albania. It is the tenth largest by area and the most populous of the twelve counties according to the 2023 Census, with about 760,000 inhabitants within an area of 1,652 km (638 sq mi).

It is divided into five municipalities, Tirana, Kamëz, Kavajë, Rrogozhinë and Vorë, with all of whom incorporate twenty-nine administrative units.

Geographically, Tirana extends from the high and rugged Skanderbeg Mountains in the east to the flat shores of the Albanian Adriatic Sea Coast along the Mediterranean Sea. Due to its location and the close proximity to the Adriatic Sea, its climate is particularly influenced by a Mediterranean climate with four distinct seasons. Two of the country's fourteen National Parks are located in the county, with Dajti in the center and Divjakë-Karavasta in the southwest.
