At this time, most edX courses are in English. Some courses are offered in other languages such as Spanish, French, or Chinese, with English subtitles available for the videos.
When you enroll in a course, you can check the course description page to determine which languages are offered for that specific course:
EdX plans to offer courses in many other languages in the near future. For translation assistance, we recommend a tool such as Google Translate.
Note: Course language options are determined by the individual course teams. While you can change the language of the edX platform in your account settings, this will not change the language of course content.
