NGC 5774 is an intermediate spiral galaxy approximately 71 million light-years away from Earth in the constellation of Virgo.[1] It was discovered by Irish engineer Bindon Stoney on April 26, 1851.[3]

NGC 5774 belongs to the NGC 5775 Group of galaxies—together with nearby NGC 5775, IC 1070, and others—which is part of the Virgo III Groups strung out to the east of the Virgo Supercluster of galaxies.[4][5] It has been classified as a "low surface brightness" (LSB) galaxy, but its central surface brightness is 5 times brighter than the brightest LSB galaxies.[5][6] It has a multiple spiral pattern with bright blue knotty structure all along the arms.[7]

It is an extremely low star forming galaxy with five X-ray sources plus three ultraluminous X-ray source candidates.[8]
