The photometric results are presented for 83 cepheids in the LMC II region which lies to the northwest of the LMC bar. The variables selected for the investigation were measured with the aid of an iris diaphragm photometer on 28 V plates and 34 B plates taken with a telescope at Boyden Observatory, South Africa in 1965-1966. The 145 suspected variables measured in the LMC II region were found to include 83 classical cepheids, one W Vir type cepheid, three eclipsing variables, ten long period variables, and one foreground RR Lyrae variable. Attention is given to the distribution of the cepheid periods, a comparison of the obtained periods with the results of other observers, amplitude-period and asymmetry-period diagrams, period-luminosity relations, the period-color diagram, the period-luminosity-color relation, the period-luminosity-amplitude and period-color-amplitude relations, and the blue edge of the instability strip in the period-luminosity and in the color magnitude diagrams of Magellanic Cloud cepheids.
