The Newall Telescope is a 62.5 centimetres (24.6 in) refractor in the Penteli Observatory in Penteli, Greece. It was built in 1869 by Thomas Cooke for Robert Stirling Newall and when completed it was the largest refracting telescope in the world. It was located at Newall's private observatory until 1891, when it was moved to the Cambridge Observatory where it stayed until its donation to the National Observatory of Athens and its move to the Penteli Observatory in 1959. The telescope is still operational, though it is only used for educational purposes.
