The objective of the study was to analyze the relationship between coral reef cover and abundance of reef fish in Marine Tourism Park of the Kapoposang Islands, South Sulawesi. This research was conducted on April 2019. Collecting coral cover data using the Underwater Photo Transect (UPT) method and coral fish data collection using Underwater Visual Census (UVC) with belt transects. The research results of coral fish found in the study site were 15 families and 54 species. The highest abundance of reef fish was foun d at site I, which was 6280 ind/ha with a percentage of live coral cover of 34% (Moderate), while the lowest abundance w as found at site III of 2100 ind/ha with a percentage of live coral cover of 5% (Poor). The relationship between the abundance of reef fish and the percentage of live coral cover can be seen in the results of the regression analysis of the value of r 2 = 0.942, this value indicates that there is a close relationship between abundance of reef fish with the percentage of live coral cover, that is if the coral cover percentage is getting better then the number of fish more abundant coral.
