3C 295 is a narrow-line radio galaxy located in the constellation of Boötes. With a redshift of approximately 0.46, it is approximately 2.05 Gpc from Earth. At time of the discovery of its redshift in 1960, this was the most remote object known.Table 1 in {{Cite journal

History

The number in its name corresponds with it being the 295th object in the Third Cambridge Catalogue of Radio Sources (which are ordered by right ascension). This is also where the prefix 3C came from.

The radio galaxy itself is a fairly normal small radio galaxy although unusually its hotspots are readily detected in optical and X-ray emission.
