NGC 5746 is a barred spiral galaxy located in the eastern part of the constellation of Virgo. It is a member of the NGC 5746 Group of galaxies, itself one of the Virgo III Groups strung out to the east of the Virgo Supercluster of galaxies.[4]

NGC 5746 is located at a distance of 99 million light years[5] and is seen nearly edge-on, bearing a strong resemblance with the galaxy NGC 4565, that is also seen nearly edge-on.
As with the former, it has a box-shaped bulge that is actually a bar seen from one side[5] and a currently modest star formation activity.[6]
Investigations with the help of the x-ray space telescope Chandra seemed to detect a large cloud of gas surrounding NGC 5746 that was thought to be remnant gas of its formation in the process of being accreted;[7] however, later research has shown that cloud does not actually exist.[8]
Seen in the infrared, NGC 5746 also shows two pseudobulges, one nested within the other – that coincides with its central bar – as well as an inner ring with a radius of 9.1 kiloparsecs and a width of 1.6 kiloparsecs.[3]
One supernova has been observed in NGC 5746: SN 1983P (type Ia, mag. 13).[9]
