Leo Minor is a small constellation in the Northern Hemisphere that is best seen in April.

Leo Minor was first introduced as a constellation by Johannes Hevelius in 1690. Leo Minor is relatively dim compared to the other lion constellation in the sky, Leo, and has no alpha star. Instead, 46 Leonis Minoris is Leo Minor's brightest star and it is called Praecipua, which means "principal star".

Leo Minor is occasionally referred to as "The Lion Cub" and "The Smaller Lion" as well as being called "The Lesser Lion."
