Amini's death was the starting point for the nationwide protests, which are now in their seventh week.
Amini died in moral police custody, days after she was arrested on charges of violating the country's strict dress code for women.
Niloofar Hamedi and Elahe Mohammadi have already been detained for over a month, accused of conspiring against the nation's security.
30-year-old Hamedi, a journalist with the newspaper Shargh, was arrested on September 20 after visiting the hospital where Mahsa Zhina Amini was treated for three days before she died.
Mohammedi, 35, was arrested after traveling to Amini's hometown of Saqqez in Iran's western, Kurdish region to report on the protests there.
The reformist newspaper Sazandegi reported in late October that more than 20 journalists are under detention in Iran for reporting on Amini's death or the subsequent protests.
The organization Reporters Without Borders (RSF) calls Iran the world's third largest prison for journalists.
More journalists are imprisoned in China and Myanmar alone.
