CCD Photometry in U, B, V and I is presented for the halo globular cluster NGC 3201. The data analyzed consist of CCD images of two fields, one centered on the cluster core and the other located at approximately 7 core radii. The fiducial sequence of NGC 3201 was compared to that of NGC 362 and it was found that the clusters are approximately coeval. The core field revealed a sequence of 31 blue stragglers which were shown not to be more centrally concentrated than subgiants of the same V magnitude range. Luminosity functions in V and I were derived using photometry from the outer field and background field. Mass-luminosity relationships (MLRs) in V and I were used to generate an isochrone, which was compared with the cluster color-magnitude diagram. The morphologies were found to be similar, lending credence to the V and I MLRs. Mass functions for the outer field in NGC 3201 were derived using both V and I data. The mass function based on the I-band measures was found to rise sharply at low masses.
