How did players qualify for the 2021 Tokyo Olympics golf competition?

The top 15 ranked players at the end of the qualifying periods were eligible for the Olympics, however there was a limit of four players in each competition from any given country. Beyond the top 15, players were eligible based on the world rankings, with a maximum of two eligible players from each country that did not already have two or more players among the top 15. The host country was guaranteed a spot, as were each of the five continental regions.
