Solution A.D. was an American rock band from northeastern Pennsylvania.

The band was initially named Solution, and appended the "A.D." after discovering that another group with the same name already existed. The group was noticed by Live guitarist Chad Taylor at a performance at CBGB, and he signed on to produce their debut EP, which was released in 1996. The group issued a full-length album soon after on Atlantic Records and toured widely behind it. The single "Fearless", taken from the full-length album, received airplay on MTV and reached No. 33 on the Billboard Modern Rock charts in 1996; it was the group's only hit.
