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 E. Weiss.
