323 Brucia (pronEng|ˈbruːsiə "brew'-see-ə," or IPA|/ˈbruːʃə/ "brew'-shə") was the first asteroid to be discovered by the use of astrophotography. It was also the first of over 200 asteroids discovered by Max Wolf, a pioneer in that method of finding astronomical objects. Discovered in 1891, it was named in honour of Catherine Wolfe Bruce, a noted patroness of the science of astronomy, who had donated $10.000 for the construction of the telescope used by Wolf.

It is also a Mars-crosser asteroid.
