1818 Brahms, provisional designation 1939 PE, is an asteroid from the inner regions of the asteroid belt. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 15 August 1939.^[3]

The asteroid orbits the Sun at a distance of 1.8–2.6 AU once every 3.18 years (1,163 days). Its orbit has an eccentricity of 0.18 and is tilted by 3 degrees to the ecliptic. Little is known about the asteroids size, composition, albedo and rotation, despite having a well-observed orbit with the lowest possible uncertainty (i.e. a condition code of 0) and an observation arc that spans over a time period of more than a century.^[1]

It is named for the German composer Johannes Brahms (1833–1897).^[2]
