Evidence is presented that Eridanus A, a cluster of galaxies centered on NGC 1407, has a mass-to-light ratio, M/L(B) about 3000 h, making it one of the darkest known clusters. Eridanus A contains only two bright galaxies, NGC 1407 and NGC 1400, and is circumscribed within about 200/h kpc, yet based on reasonable assumptions, it has a virial mass about 7 x 10 exp 13 solar masses/h. The high mass and high M/L estimates rest heavily on the supposition that NGC 1400, which has a peculiar velocity about 1100 km/s, is truly a cluster member and not a foreground object. All the available data and all reasonable alternatives are examined, and it is concluded that NGC 1400's membership in Eridanus A is the most plausible and conservative explanation for the known facts.
