The name Fenais da Ajuda comes from fenais (hay or other herbaceous plants used as animal fodder, since the area historically produced much animal fodder), and from its patron saint, Nossa Senhora da Ajuda (Our Lady of Assistance), and a Franciscan monastery to Her honour that was located in the parish.
