Boötes, pronounced with both 'O's as 'boötez', is one of the 88 modern constellations in the northern sky. The name is from the Greek word Βοώτης, which means herdsman – someone who takes care of animals.
The constellation's shape is like a kite. Boötes has the third brightest star in the night sky, called Arcturus (α Bootis). The astronomer Ptolemy listed it in the 2nd century when he made a list of 48 constellations.
The Cloverleaf quasar is visually in Bootes.
- α Bootis (Arcturus) is the brightest and most important star of the constellation, with a magnitude of -0.04, the 3rd brightest star of the sky. It is an orange giant star

Boötes as depicted in Urania's Mirror, a set of constellation cards published in London c.1825. In his left hand he holds his hunting dogs, Canes Venatici. Below them is the constellation Coma Berenices. Above the head of Boötes is Quadrans Muralis, now obsolete, but which lives on as the name of the early January Quadrantid meteor shower. Mons Mænalus can be seen at his feet.
