V450 Aquilae is semi-regular pulsating star in the constellation Aquila. Located around 660 light-years distant, it shines with a luminosity approximately 2,172 times that of the Sun and has a surface temperature of 3,326 K. The star varies in brightness from magnitude from 6.14 to 6.86, so when it is at its brightest, it will be faintly visible to the naked eye.

Cuno Hoffmeister announced that V450 Aquilae was a newly discovered variable star in 1935. Its period is 64.2 days.
