1567 Alikoski, provisional designation 1941 HN, is a rare-type carbonaceous asteroid from the outer region of the asteroid belt, approximately 67 kilometers in diameter. It was discovered on 22 April 1941, by Finnish astronomer Yrjö Väisälä at Turku Observatory in Southwest Finland.^[11] It was later named after Finnish astronomer Heikki Alikoski.^[2]

This asteroid orbits the Sun in the outer main-belt at a distance of 2.9–3.5 AU once every 5 years and 9 months (2,101 days). Its orbit has an eccentricity of 0.08 and an inclination of 17° with respect to the ecliptic.^[1] Alikoski's observation arc begins with a precovery taken at Turku in 1938, extending it by 3 years prior to the asteroid's official discovery observation.^[11]

This minor planet was named in honor of Finnish astronomer Heikki Alikoski (1912–1997), assistant to the discoverer from 1937 to 1956, and an observer and discoverer of minor planets himself. He also helped greatly in establishing the Turku Astronomical-Optical Institute.^[2] The official naming citation was published by the Minor Planet Center on 20 February 1976 (M.P.C. 3930).^[12]
