NGC 3806 is an intermediate spiral galaxy located in the constellation Leo.[2] Its velocity relative to the cosmic microwave background is 3829 ± 24 km/s, which corresponds to a Hubble distance of 56.5 ± 4.0 Mpc (∼184 million ly).[2] NGC 3806 was discovered by Prussian astronomer Heinrich d'Arrest in 1862.[3]

Opinions differ on the classification of NGC 3806. The NASA/IPAC and LEDA databases list it as an intermediate spiral and Professor Seligman and Wolfgang Steinicke call it a barred spiral. The luminosity class of NGC 3806 is II and it has a broad HI line.[1]
