Elizabeth Ahern (19 October 1877 – 7 April 1969) was an Australian political activist, trade unionist and socialist.

[1][2] Ahern joined the Abbotsford branch of the Political Labor Council in 1904, and the Social Questions Committee, later renamed the Victorian Socialist Party, the following year.

The Victorian Socialist Party was primarily interested in education and free speech and ran weekly meetings in the Bijou Theatre that often attracted crowds of more than 1,000 people.

Ahern was one of the Party's most popular and effective speakers and spoke at their meetings on street corners as well as in rural areas.

She was a delegate to the Political Labor Council's annual conference in 1907 and helped to establish the Domestic Workers' Union and the Women's Socialist League.
