Hippolyte Havel (August 11, 1871 – March 10, 1950) was an American anarchist who was known as an activist in the United States and part of the radical circle around Emma Goldman in the early 20th century.

Then in the British metropolis he met anarchist Emma Goldman on a lecture tour from the United States.

[4] He managed to flee to London, where, in November 1899, he met the American anarchist and activist Emma Goldman, who was on a lecture tour.

Havel traveled with Goldman from Europe to the United States, entered as an immigrant, and settled in Chicago.

[5][6] In September 1901, Goldman, Havel, Isaak, and ten other anarchists were arrested as suspects in connection with Leon Czolgosz's assassination of President William McKinley.

Sometime in the early 1900s, he and Goldman moved to New York City, where they lived in Greenwich Village, a center of radical politics and artists and writers.

He also contributed dozens of articles and essays to anarchist journals, including Goldman's Mother Earth.
