We present CCD measurements taken in UBVRI broadband filters on 2008 19 January using the WIYN 0.9m telescope at Kitt Peak National Observatory under photometric conditions for metal-poor open star cluster NGC 2506. Comparison of color-color diagrams for the cluster fiducial sequence to the Hyades yields a metallicity, [Fe/H] = -0.45+/-0.10, and reddening, E=0.10+/-0.01. Comparison of color-magnitude plots to the Yale-Yonsei 2002 isochrones yields: (m-M)v=12.76+/-0.05 and age=2.10+/-0.05Gyr.
