Percival Lawrence Lowell (13. mart 1855. – 12. novembar 1916.) bio je američki biznismen, književnik, matematičar, i astronom koji je podgrijao razmišljanje o tome da postoje kanali na Marsu. On je osnovao Lowell opservatoriju u Flagstaffu, Arizona, i oblikovao početne napore koji su vodili otkriću Plutona 14 godina nakon njegove smrti.
