IC 1953 is a barred spiral galaxy situated in the constellation of Eridanus. Located about 83.4 million light years away,[2] it is a member of the Eridanus cluster of galaxies, a cluster of about 200 galaxies. It was discovered by DeLisle Stewart in 1899.[3]

IC 1953 has a Hubble classification of SB(rs)d, which indicates it is a barred spiral galaxy. It is moving away from the Milky Way at a rate of 1,867 km/s. Its size in the night sky is 2.9' x 2.1', which is proportional to its estimated size of 88,000 ly.
