you can do like this after having the user permission var user_id = 'USERID' var page_id = 'YOUR PAGE ID'; var fql_query = 'SELECT uid FROM page_fan WHERE page_id = ' + page_id + ' and uid='+ user_id; var query = FB.Data.query(fql_query); query.wait(function (rows) { if (rows.length == 1 && rows[0].uid == user_id) { //IS A FAN OF THE PAGE } else { //NOT A FAN OF THE PAGE } });
