The present study aims to identify the avant-garde role of the private sector, and its significance in achieving the sustainable and comprehensive development in Najran Area, as an example for the local development in the Kingdom of Saudi Arabia. It also aimed at identifying the challenges that impede the complete fulfillment of the role in realizing the comprehensive development. The researcher utilized the historical, descriptive, and analytical method in this study. The questionnaire was relied upon as a main data collection instrument. The study population consisted of the private sector organizations in the area. The author distributed the questionnaire to (96) owners of these organizations, who were taken as the study sample, which was selected through a simple random manner. The results of the study indicated that the private sector in the area produces products that realize self-sufficiency of the area population. This sector further has an effective role in reducing unemployment, finding job opportunities for the Saudi citizen, increasing his income, and contributing to the realization of the social security in the area. Most importantly, the projects of this sector are mainly environment friendly.
