Photographic BVRI color-magnitude and color-color diagrams are provided for 14 star clusters situated in the Bok region of the Large Magellanic Cloud. Eleven have NGC numbers: 1834, 1836, 1839, 1847, 1850, 1854, 1856, 1858, 1860, 1863, 1870; the remaining three are from the SL (Shapley-Lindsay) catalog: 234, 237, and 304. None of these clusters have had previous stellar photometry in R and I, and only four of them in B and V.The reddening for each cluster has been estimated by fitting the main sequence of the CMDs to the unreddened ZAMS. Ages have been derived from the MS turnoff and from the brightest blue star following the method developed by Hodge (1983), and from fitting the CMDs to the isochrones of Maeder and Mermilliod (1981). All clusters are found to be young, with ages ranging from 17 + or - 6 x 10 to the 6th yr for NGC 1858 to 90 + or - 30 x 10 to the 6 yr for NGC 1860. They lie symmetrically in the center of the age histrogram of galactic clusters (Lynga 1982). Both distributions peak close to log(t) approximately 7.5.
