Macedonian Americans (Macedonian: Македонски Американци) are Americans of ethnic Macedonian heritage.

Macedonian national feelings had shifted throughout the 20th century. According to the Harvard Encyclopedia of American Ethnic Groups, almost all of Macedonians in the U.S. until World War II classified themselves as Macedonian Bulgarians or simply as Bulgarians. Nevertheless, the Bulgarian national identification during the late Ottoman Empire, from where most of the emigrants arrived, was based on ethno-religious principles and still ambiguous. Macedonian immigrants identified also as Macedonians. Early 20th century census documents and newspaper articles mention Macedonian language/mother tongue and race/nationality, but that designation was used then mainly as a regional identification. The sense of belonging to a separate Macedonian nation did not get strongly established until after World War II, following the founding of the People's Republic of Macedonia within the Socialist Federal Republic of Yugoslavia and the codification of a distinct Macedonian language.

The first Macedonian immigrants to the U.S. arrived in the late 19th century from the Bansko region of what is today Bulgarian Macedonia. These Macedonians had often been educated by American missionaries and were encouraged to migrate to the United States for higher education or to attend missionary schools. But the first large swath of Macedonians came in the early 20th century from the border regions in the north of what is today Greek Macedonia, primarily the regions near Kastoria (Kostur), Florina (Lerin), and the south-west of North Macedonia, notably around Bitola. These Macedonians had faced the greatest retributions from the Ottoman military because the 1903 Ilinden uprising was centered in these areas.

In December 1918 a congress was held in Chicago, lasting a week, where c. 200 attended. Given events in the First World War, and the break-up of the Ottoman Empire, local organizers prepared a proposal about the eventual after-war status of Macedonia. By a great majority, the delegates supported a proposal for annexation to Bulgaria. In January 1919, after Bulgaria lost the war, the Macedono-Bulgarian Central Committee in the US sent a report to the Great Powers. They explained their view of the real motives of Bulgaria to enter the war and demanded that Macedonia be joined to Bulgaria.

In the 1920s, many Macedonian-Americans became very suspicious that the main Macedonian organization at that time – the Macedonian Patriotic Organization, existed to advance Bulgaria's political interests. Some Macedonian-Americans began to form smaller clubs and societies whose members were limited to fellow villagers. Members of these small groups could trust the others in their group, and they knew that they were not being taken advantage of by the leaders of the MPO.

During the 1930s, some ethnic Macedonians began to identify as "Macedonian", and promoted this new ethnic identification, following political directives. The first organization in North America to support the idea that Macedonians constitute a separate nationality was the pro-communist Macedonian People's League, which was active in the US and Canada. MPL, which was financially supported by the Soviet Union, acted aggressively against the MPO, which it believed was a Bulgarian weapon.

Immigration restarted after the wars; most of the new immigrants were from Greece, many of whom had been expelled from Greek Macedonia in the 1920s. The immigrants' organizations used the Bulgarian language in their official documents, but since the 1920s and 1930s the Macedonian language has been recorded in American censuses. Several Macedonian immigrants also claimed to use Macedonian as their native tongue in the 1910 U.S. Census.

The aftermath of the war led to a fresh round of Macedonian immigration; 70,000 emigrated to Canada, Australia, the U.S., and other European countries.
