The Van's RV-9 and RV-9A are American two-seat, single-engine, low-wing homebuilt airplanes sold in kit form by Van's Aircraft of Aurora, Oregon. The RV-9 is the tail-wheel equipped version while the RV-9A features a nose-wheel.

The RV-9 was built around a newly designed high aspect ratio wing, featuring a Roncz airfoil. It is similar in size and weight to the RV-6 and is externally similar to the RV-6 and the RV-7.

The architect of the line of Van’s aircraft, Richard VanGrunsven, designed the RV-9 as a departure from the concepts of the earlier RV series. The earlier members of the RV series, starting with the single seat RV-3, were all designed to have light handling, aerobatic capabilities along with fast cruise speeds and short field STOL capabilities. The RV-9 was designed from the start as a two-place, side-by-side, touring aircraft and as such it forgoes the aerobatic capabilities and the lighter handling for more stability and economy. As such the design horsepower is 118-160 and the prototype was flown with a Lycoming O-235 powerplant of 118 hp (88 kW) as a proof-of-concept for the lower horsepower.

As a result of the lessons learned over the years in producing the first five RV-series designs and the change in role for this aircraft, the RV-9 design incorporated many changes over previous designs.

The RV-9A was the first to use what Van's calls "matched-hole" components in that airframe parts are formed to the required contour and have all the rivet holes precisely located. The assembly jigs normally used to ensure alignment are not necessary and build time is much reduced. Later models, such as the RV-7 and RV-10, use this same manufacturing technique.

Compared to the similar RV-7, the RV-9 has a wing of increased span and higher aspect ratio using a Roncz airfoil. The RV-9 has a slow stall speed, comparable to the Cessna 150, and docile handling suitable for low-time pilots. The cruise speed is a very respectable 167 mph (269 km/h) TAS even with the 118 hp (88 kW) engine.
