The Van's RV-3 is a single-seat, single-engine, low-wing kit aircraft sold by Van's Aircraft. Unlike many other aircraft in the RV line, the RV-3 is only available as a tail-wheel equipped aircraft, although it is possible that some may have been completed by builders as nose-wheel versions. The RV-3 is the genesis design for the rest of the RV series, all which strongly resemble the RV-3. The RV-4 was originally developed as a two-seat RV-3.

Van's Aircraft, Inc. is an American kit aircraft manufacturer founded by Richard "Van" VanGrunsven in 1973. The Van's RV series aircraft are all-aluminum, low-wing monoplanes of monocoque construction. In 2023, over 11,000 Van's aircraft were flying worldwide, one third of the USA's experimental aircraft fleet.
