The Piper PA-34 Seneca is a light aircraft, often used for personal transport. It is a twin-engine version of the PA-32 Cherokee Lance series.

Since its introduction in 1971 as the PA-34-200 Seneca I, the aircraft has undergone many changes. In 1975, responding to complaints about the aircraft's handling qualities, Piper introduced the PA-34-200T Seneca II. The new model incorporated changes to the aircraft's control surfaces, including enlarged and balanced ailerons, the addition of a rudder anti-servo tab, and a stabilator bobweight. The "T" in the new model designation reflects an upgrade to turbocharged, six cylinder TSIO-360 Continental engines for improved performance. Overall, the changes were effective, but the aircraft was still considered to feel somewhat heavy in flight.

Its major competitive aircraft was the Cessna 337 centerline thrust aircraft.

In 1981, the PA-34-220T Seneca III was introduced. The change in model designation reflects an engine upgrade. This time, a different variant of the Continental engines were used with 220 horsepower (165 kW), although only rated as such for five minutes and then dropping to 200 hp (150 kW). The horsepower increase, combined with the new engines' rev limit of 2800rpm (up from 2575rpm), combined for much improved climb and cruise performance. The new aircraft also incorporated a one piece windshield, larger, electrically actuated flaps and a less flimsy instrument panel made of thicker plastic.

After the major upgrades of the Seneca II and III, model revisions were less drastic. In 1994, the "New" Piper company introduced the Seneca IV. This aircraft was much the same as the Seneca III but offered a streamlined engine cowl for increased cruise performance. Finally, in 1998 the Seneca V was released. Again the cowls were redesigned for increased performance, several cockpit switches were relocated from the panel to the headliner and a slightly different engine variant was used, but this aircraft is very similar to the III and IV models.
