Objectives: Cephalometric norms derived for Caucasian population are routinely used for investigations. As these norms show a great degree of variation when applied to different populations, it becomes necessary to establish the norms for every ethnic group. The present study was designed to derive norms for the Maratha ethnic population, which would be comparable in diagnosis and treatment planning, to the Steiner, Tweed, Ricketts and McNamara cephalometric analysis. Materials and Methods: The sample consisted of 60 adult subjects (30 males and 30 females) of Maratha ethnic origin. The age ranged between 18 and 26 years. The cephalograms of the subjects were subjected to Steiner, Tweed, Ricketts and McNamara cephalometric analysis and were complemented by a few additional readings. Result: The cephalometric norms for Steiner, Tweed, Ricketts and McNamara cephalometric analysis of the Maratha population differed significantly from the Caucasian population. Comparison of our sample with the other ethnic group reaffirmed the need to develop separate standards for different populations. Conclusion: Therefore, it is legitimate and important for those undertaking orthodontic treatment for patients of Maratha ethnicity to use cephalometric norms for Maratha ethnic population
