NGC 4244, also known as Caldwell 26, is an edge-on loose spiral galaxy in the constellation Canes Venatici, and is part of the M94 Group or Canes Venatici I Group, a galaxy group relatively close to the Local Group containing the Milky Way. In the sky, it is located near the yellow naked-eye star, Beta Canum Venaticorum, but also near the barred spiral galaxy NGC 4151 and irregular galaxy NGC 4214.

With an apparent V-band magnitude of 10.18,[3] NGC 4244 lies approximately 4.3 megaparsecs[3] (14 million light years)[6] away. A nuclear star cluster and halo is located near the centre of this galaxy.[6][7]
