3C 295 is a narrow-line radio galaxy located in the constellation of Boötes.

[4] 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).

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

3C 295's cluster has enough material to create another 1,000 galaxies or more, making it one of the most massive objects in the known Universe.

However, X-ray data showed that there is not enough mass to hold 3C 295 together gravitationally, which suggests the presence of dark matter.
