Dresda (minor planet designation: 263 Dresda) is a typical Main belt asteroid. It belongs to the Koronis family of asteroids.
It has a lightly coloured surface and likely is not composed of carbonaceous materials, but is similar in composition as another Koronis family member, 243 Ida.
It was discovered by Johann Palisa on 3 November 1886 in Vienna.
The asteroid's name derives from the Germany city of Dresden.
