1245 Calvinia, provisionally designated 1932 KF, is a stony main-belt asteroid with a diameter of about 27 kilometers. It orbits the Sun with a period of 4.92 years at a distance of 2.7–3.1 AU. The S-type asteroid has a high albedo of 0.27 and is therefore relatively bright for its size. Calvinia has been measured to rotate around its axis every 4.84 hours. It was discovered by astronomer Cyril Jackson at Johannesburg Union Observatory, South Africa, on May 26, 1932.
This asteroid was named after the regional city Calvinia in the Cape Province of South Africa.
