This is a list of voids in astronomy. Voids are particularly galaxy-poor regions of space between filaments, making up the large-scale structure of the universe. Some voids are known as supervoids.

In the tables, z is the cosmological redshift, c the speed of light, and h the dimensionless Hubble parameter, which has a value of approximately 0.7 (the Hubble constant H0 = h × 100 km s−1 Mpc−1). Mpc stands for megaparsec.

The evidence for such a "Great Void" is disputed by Smith and Huterer.[13] They showed that the claims made of observational evidence for such a void from survey data neglected systematic effects and did not account for a posteriori choices made in analyzing data.

In 1985, Tully determined a local dominant supercluster plane, and found the Pisces–Cetus Supercluster Complex.[22]

A 1994 census lists a total of 27 supervoids within a cube of 740 Mpc a side, centered on us (z=0.1 distant sphere).[25]
