The Bayer designation ρ Eridani (Rho Eridani, ρ Eri) is shared by three stars in the constellation Eridanus that lie in a line: ρ1 Eridani (8 Eridani) ρ2 Eridani (9 Eridani) ρ3 Eridani (10 Eridani)

Johann Bode later applied ρ4 to the star HD 19349, however it was not widely adopted and disused afterwards.
