Per Lindstrand (born 8 September 1948) is a Swedish aeronautical engineer, pilot, adventurer and entrepreneur. He is particularly known for his series of record-breaking trans-oceanic hot air balloon flights and, later, attempts to be the first to fly a Rozière balloon around the Earth – all with British entrepreneur, Sir Richard Branson. He is also the founder of eponymous Lindstrand Balloons hot air balloon manufacturer based in Oswestry, England.

Lindstrand not only flies balloons, but many other aircraft as well, and holds an airline transport pilot's licence for single and multi-engined land and sea aeroplanes and helicopters, and a commercial pilot's licence for autogyros, airships and gliders. His long standing dream to make a flight around the world in a hot air balloon (as opposed to a Rozière or gas balloon which requires no constant source of heated air) still remains unrealized. His distance, duration and altitude records have made him one of the best known balloonists and aerostat designers and engineers in the world.

Lindstrand's aeronautical career began in the Swedish Air Force where he was an Engineering Officer. His first balloon flight in the early 1970s was the result of a bet. He built a makeshift balloon and successfully flew it across the runway while in the Swedish Air Force to claim victory. (When he flew more conventional military aircraft, he chose to use call sign, Polar Per.)

Lindstrand later gained a master's degree in aeronautical engineering and worked for Saab Aircraft in Sweden and Lockheed in the United States.

With Swedish aircraft engineer and entrepreneur, Håkan Colting, he formed Colting Balloons which operated in Ireland from 1976. In 1978 the company moved to Oswestry, England, to be closer to major markets in the UK and Europe. When Håkan Colting moved to Canada, Lindstrand continued to run the renamed Colt Balloons (later Thunder & Colt Balloons after acquiring UK-based Thunder Balloons).

In December 1991 Lindstrand founded Lindstrand Balloons Ltd. and later created a specialized aerospace company, Lindstrand Technologies Ltd. (both based in Oswestry) to manufacture and repair aerostats, airships, gas balloons, passenger-carrying tethered aerostats and other fabric engineering products (including architectural structures, innovative fire-safety devices for road tunnels and inflatable flood defence barriers). In 2002, Lindstrand Balloons was asked to manufacture the complex parachute for the Mars-lander, Beagle 2. Beagle 2 was launched in June 2003, but supposedly failed to land successfully on the Planet Mars on Christmas Day 2003. However, in January 2015 was it located on the surface of Mars in a series of images from NASA's Mars Reconnaissance Orbiter HiRISE camera. The images suggest that it landed safely, but two of the spacecraft's four solar panels failed to deploy, blocking the spacecraft's communications antenna.

Lindstrand Balloons, in partnership with Daimler Chrysler Aerospace of Germany, was awarded a design contract by the European Space Agency to develop a high altitude long endurance airship for possible use in the telecommunications market. Resulting from this, Lindstrand was awarded the German-based Korber Prize for engineering excellence.

From early in his business career, Lindstrand's main interest and ambition lay in pushing the boundaries of lighter-than-air technology and he subsequently captured every absolute world record for hot air balloon flight.
