Diagram caption: The constellation Lupus with its bright stars and surrounding constellations. Lupus is surrounded by (going clockwise from the top): Libra, Hydra, Centaurus, Circinus, Norma and Scorpius.

Lupus is a southern constellation and thus the whole constellation is visible at some point in the year throughout the southern hemisphere. The whole constellation is visible in equatorial and some temperate regions of the northern hemisphere with parts of the constellation visible to remaining temperate regions. Lupus is best viewed in the evenings in the northern hemisphere summer and southern hemisphere winter.

The y-axis of this diagram is in degrees of declination with north as up and the x-axis is in hours of right ascension with east to the left. The sizes of the stars marked here relate to the star's apparent magnitude, a measure of its apparent brightness. The larger dots represent brighter stars. The Greek letters mark the brightest stars in the constellation. These are ranked by brightness with the brightest star being labeled alpha, the second brightest beta, etc., although this ordering is not always followed exactly. The dotted boundary lines mark the IAU's boundaries of the constellations and the solid green lines mark one of the common forms used to represent the figures of the constellations. The blue line in the top left of the diagram marks the ecliptic. Neither the constellation boundaries, nor the line marking the ecliptic, nor the lines joining the stars appear on the sky.
