NGC 5749 is an open cluster of stars positioned near the southwest border of the southern constellation of Lupus.

It is located at a distance of 3,548 light years from the Sun.

[1] This is a poorly populated cluster that shows a low level of concentration;[6] the Trumpler class is IV1p.

[7] There are 112 stars brighter than magnitude 14.4 within an angular radius of ~15′ of the cluster center, but only about 30% of these are members.

[3] Polarization measurements suggest there is a dust cloud within the cluster.
