NGC 5584 is a barred spiral galaxy[8] in the constellation Virgo.

[10] Distance determination using Cepheid variable measurements gives an estimate of 75 million light years,[6] whereas the tip of the red-giant branch approach yields a distance of 73.4 million light years.

[11] The morphological class of NGC 5584 is SAB(rs)cd,[8] which indicates this spiral galaxy has an inner bar (SAB), an incomplete inner ring structure (rs), and loosely wound spiral arms (cd).

Star formation is occurring along the spiral arms.

[8] The galactic plane is inclined at an angle of 42.4° to the line of sight from the Earth,[7] and it spans more than 50,000 light-years across.
