The Tecnam P2002 Sierra is a two-seat, low-wing, light aircraft designed and constructed by the Italian aircraft manufacturer Tecnam. Introduced during the early 2000s, the aircraft quickly became a staple of the company's product lineup, comprising 70 per cent of its available production capacity during some years.

Costruzioni Aeronautiche TECNAM S.p.A., commonly known as simply Tecnam, is an Italian aircraft manufacturer. The company has two primary activities: producing aircraft components for various other manufacturers, and manufacturing its own range of light aircraft. The company was founded in 1986 by Italian brothers Luigi Pascale and Giovanni Pascale, veteran aircraft designers and manufacturers. Prior to creating Tecnam, they had been responsible for several other aviation-related projects, including the design and construction of the twin-engine Partenavia P.68. Their original intent in founding Tecnam was to build aerospace parts on behalf of other manufacturers, which initially included American aerospace company Boeing and commuter airliner specialist ATR. When the light-sport aircraft market began to emerge, the brothers entered the field, first with the Tecnam P92, which was well received.
