781 Kartvelia is a minor planet orbiting the Sun that was discovered by Georgian–Russian astronomer Grigory Neujmin on January 25, 1914. Kartvelia comes from the historic name for the inhabitants of the nation of Georgia.^[3] This object is orbiting at a distance of 3.22 AU with an eccentricity (ovalness) of 0.12 and a period of 5.78 yr. The orbital plane is inclined at an angle of 19.1° to the plane of the ecliptic.^[2]

This asteroid is rotating with a period of 19.0 hours and spans an estimated girth of 66 km. It is tentatively classified as type CPU in the Tholen taxonomic system, with the C indicating a carbonaceous object.^[2] This is the namesake of a family of 49–232 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.^[4]
