The Pottier P.70 was a single-seat, single-engine sport aircraft developed in France in the 1970s and marketed for homebuilding. It was a mid-wing cantilever monoplane of conventional design with an enclosed cockpit. Originally designed with fixed, tricycle undercarriage, the plans were later revised to offer a fixed, tailwheel option. Construction throughout was of metal. A two-seat, tandem version was developed as the P.170.
