Škoda 24Tr Irisbus (known as Irisbus Skoda 24Tr in Western Europe) is a low-entry trolleybus model built from 2003 until 2014 by Czech trolleybus manufacturer Škoda Electric (subsidiary of Škoda Transportation), supplying electrical equipment, in cooperation with Irisbus, supplying body.

After a relatively successful effort to unify bus and trolleybus (Karosa ŠM 11/Škoda T-11, Karosa B 831/Škoda 17Tr and Skoda 21ab/Škoda 21Tr), Czechs took fourth attempt, and created a trolleybus Škoda 24Tr.

Trolleybus is a low floor, only the back of the seats on the stand.

On the right side, there are three double doors with a "stop" button, which opens at the passenger's request.

The first trolleybus was built on the Citybus bus-based (based on the roof of CNG-based).
