229 Adelinda is a large, dark outer main-belt asteroid. It is classified as a C-type asteroid and is probably composed of primitive carbonaceous material.
It is part of the Cybele asteroid group and probably in 4:7 orbital resonance with planet Jupiter.
It was discovered by Johann Palisa on August 22, 1882, in Vienna.
It was named after Adelinda, wife of astronomer Edmund Weiss.
