2175 Andrea Doria, provisional designation 1977 TY, is a small, stony asteroid in the inner parts of the asteroid belt. It was discovered on October 12, 1977 by astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland. The S-type asteroid orbits the Sun at a distance of 1.8–2.7 AU once every 3 years and 4 months (1,205 days). It rotates around its axis with a period of 4.9 hours.
Andrea Doria belongs to the Flora family of asteroids. Although it is a small asteroid of just 4 kilometers in diameter, its surface is very reflective with a geometric albedo of almost 0.4, making it possible to be observed at an absolute magnitude of 13.8.
It is named after the 16th-century Genoese admiral Andrea Doria, popularized in Friedrich Schiller's drama Fiesco. Several ships, including the SS Andrea Doria, famous for its sinking off the coast of New England, had also been named after the admiral.
