Ajax Records has been the name of at least two different record labels.

The first Ajax Records was a North American record company, active in Canada and the United States of America from 1921 through 1926.

The head of Ajax Records was H. S. Berliner, son of disc record pioneer Emile Berliner. Berliner's corporate headquarters were in Quebec City, Quebec, although US issues listed the company as being based in Chicago, Illinois, where its US office was located, but apparently no recording studio. Ajax is known to have had recording studios in Montreal and New York City. The audio fidelity of Ajax discs is above average for the time. Distribution of Ajax records in the USA outside of the north-east and north-central part of the nation seems to have been poor.

In addition to the sides which Ajax recorded themselves, the label also issued discs pressed from masters leased from Pathe Records and the Plaza Music Company .

At the end of the 20th century there was a different Ajax Records (info needed)
