The PA-34 was developed as a twin-engine version of the Piper Cherokee Six. The Piper Seneca model prototype was a Cherokee Six with wing-mounted engines installed, retaining its nose engine. This prototype was flown as a tri-motor aircraft in the first stages of the test-flying program.

The decision was made to forego the three-engined design and develop a twin-engined design. First flown in 1967 the PA-34-180 Twin Six had two 180 hp Lycoming O-360 engines, a fixed nosewheel landing gear, and a Cherokee Six vertical tail. In 1968, the second prototype featured retractable landing gear and a taller vertical tail. Throughout development the wingspan was increased by two feet. Fitted with 200 hp Lycoming IO-360-A1A engines the third prototype flew in 1969.

The PA-24-200 Seneca I was certified and introduced in 1971 as a 1972 model. The Seneca I is powered by a pair of Lycoming IO-360-C1E6 engines. The aircraft's righthand engine is a Lycoming LIO-360-C1E6 engine variant. The "L" indicating that the crankshaft turns in the opposite direction, giving the aircraft counter-rotating engines. The counter-rotating engines make the Seneca I more controllable in the event of a shut down or failure of either engine.

The new PA-34-200T Piper Seneca II was introduced in 1974 as a 1975 model. The Seneca II features changes to the aircraft's control surfaces, including enlarger and balanced ailerons, a stabilator bobweight, and the addition of a rudder anti-servo tab. The aircraft is powered by turbocharged, six-cylinder Continental TSIO-360E or EB engines. The Seneca II retained the counter-rotating engine arrangement. Optional "club seating" was also introduced.

The PA-34-220T Piper Seneca III was introduced in 1981. The Seneca III featured upgraded Continental TSIO-360-JB engines. Introduced in 1994, the PA-34-220T Seneca IV was similar to the Seneca III offering minor improvements, such as a streamlined engine cowl. The cowls were redesigned to increase performance, several cockpit switches were relocated from the panel to the headliner and a slightly different engine variant, the Continental TSIO-360-RB was installed on the Piper Seneca V. The Seneca was also built under license by Embraer in Brazil as the EMB-810. The Seneca is operated by private individuals and companies, as well as air charter companies and small feeder airlines.
