350 Ornamenta is a relatively large main-belt asteroid, measuring 118 km in diameter. It is classified as a C-type asteroid and is probably composed of carbonaceous material.

Ornamenta was discovered by Auguste Charlois on December 14, 1892, in Nice, France. It was named in 1905 after Antoinette Horneman, who was a member of the Société astronomique de France.[2]

This object is the namesake of a family of 14–93 asteroids that share similar spectral properties and orbital elements; hence they may have arisen from the same collisional event. All members have a relatively high orbital inclination.[3]
