You may be. Technically, if your mother is Jewish you're Jewish. So, if your mother's mother was Jewish your mother was Jewish and you're Jewish. However, if your mother wasn't raised Jewish and/or converted to another religion and you weren't raised Jewish, you might have to undergo conversion to Judaism if you wish to live as a Jew. This is something you would need to discuss with a rabbi.
