At least eight women and one man are reported to have been sentenced to death by stoning in Iran.
The group, convicted of adultery and sex offences, could be executed at any time, lawyers defending them say.
The lawyers have called on the head of Iran's judiciary to prevent the sentences from being carried out.
The last officially reported stoning in Iran last year drew strong criticism from human rights groups and the European Union.
The eight women sentenced, whose ages range from 27 to 43, had convictions including prostitution, incest and adultery, Reuters news agency reported.
The man, a 50-year-old music teacher, was convicted of illegal sex with a student, reports said.
