1150 Achaia is a main-belt asteroid orbiting the Sun with a period of 3 years and 4 months. It was discovered by German Karl Reinmuth at Heidelberg Observatory, on September 2, 1929. Ten days later, it was independently discovered by Schwassmann and Wachmann at Bergedorf Observatory near Hamburg. Its provisional designation was 1929 RB.^[1]

It is named after the Greek region Achaea in the northern Peloponnese, bordering on the gulfs of Corinth and Patras. The alternative spelling "Achaea" for the province is also used.^[2]
