An American woman charged with subversion in Zimbabwe for allegedly insulting President Robert Mugabe on Twitter is set to be freed on bail.

Martha O'Donovan on Thursday was ordered freed on $US1,000 bail but the New Jersey woman will return to court on Wednesday.

O'Donovan is accused of calling the 93-year-old Mugabe a "sick man" in a tweet including an image of the president with a catheter.

O'Donovan faces up to 20 years in prison if convicted for subversion. She also faces a charge of undermining the authority of or insulting the president, which carries up to a year in prison.

O'Donovan has denied the charges as "baseless and malicious."

Hers is the first arrest since Mugabe last month appointed a cybersecurity minister, criticised by activists as targeting social media.
