Psi Serpentis (ψ Ser / ψ Serpentis) is a star system in the constellation Serpens. It is approximately 47.9 light years from Earth.

The primary component, Psi Serpentis A, is a yellow G-type main sequence dwarf with an apparent magnitude of +5.86. It has a close 12th magnitude companion, Psi Serpentis B, 4.2 arcseconds, or at least 60 Astronomical Units, distant.

Orbiting this pair with a separation of 3.5 arcminutes is the +8.8 magnitude K-type Psi Serpentis C. Slightly closer, at a distance of 2.9 arcminutes, is the +10.4 magnitude Psi Serpentis D. The brightest companion, Psi Serpentis E, a magnitude +7.1 G-type giant, is also the most distant, being separated from the primary by 5.9 arcminutes, or at least 5200 Astronomical Units.Fact|date=February 2007
