NGC 6509 is a spiral galaxy in the equatorial constellation of Ophiuchus. It was discovered on July 20, 1879 by the French astronomer Édouard Stephan. This galaxy is located at a distance of 95.3 million light-years (29.22 Mpc) from the Milky Way, and is receding with a heliocentric radial velocity of 1,814 km/s.

This is a bulge-less disk galaxy with a morphological classification of Sd. The plane of the galaxy is inclined at an angle of 41°±4° to the plane of the sky, and the oval outline is oriented along a position angle of 280.8°±1.1° with an angular span of 1.6′.

The eastern side of this galaxy lies in the foreground of a radio source designated 4C +06.63.
