(263) Дрезда (нем. Dresda) — небольшой астероид главного пояса, входящий в состав семейства Корониды. Поверхность этого астероида отражает довольно много солнечного света, поэтому Дрезда состоит не из углеродсодержащих материалов, а имеет такой же состав, что и другой представитель данного семейства — астероид (243) Ида.
