Horologium is a small and faint constellation in the southern sky (declination around −60 degrees). Its name is Latin for clock.[1] It was created in the 18th century by Abbé Nicolas Louis de Lacaille, who originally named it Horologium Oscillitorium after the pendulum clock to honour its inventor, Christiaan Huygens. The name has since been shortened to be less cumbersome.

One of the few objects of interest to amateur observers is R Horologii, a Mira variable with one of the largest magnitude ranges known. The globular cluster AM1 is found in the constellation, the most remotely known globular cluster in the Milky Way at a distance of 398 000 light years.
