Jacob ben Nathanael ibn al-Fayyumi () was a rosh yeshiva of the Yemenite Jews in the second half of the 12th century CE, son of the illustrious Rabbi, Nathanel al-Fayyumi. All that is known of him is that at the suggestion of Solomon ha-Kohen, a pupil of Maimonides, he wrote to the latter asking his advice in regard to a pseudo-Messiah who was leading the Jews of southern Arabia astray.
