HR 1613, a barely naked-eye star in the constellation of Orion, is one of a number of bright, early-type stars that have few or no previous radial velocity measurements. Our observations show that it is a single-lined spectroscopic binary with a period of 8.11 days and a circular orbit. It has a spectral type of A9 V and is slowly rotating with v sin i = 12 km/s. The unseen secondary star is likely an M dwarf.
