The Straight Story is a 1999 biographical road drama film directed by David Lynch. It was edited and produced by Mary Sweeney, Lynch's longtime partner and collaborator, who also co-wrote the script with John E. Roach. It is based on the true story of Alvin Straight's 1994 journey across Iowa and Wisconsin on a lawn mower.

Alvin (Richard Farnsworth) is an elderly World War II veteran who lives with his daughter. When he hears that his estranged brother has suffered a stroke, Alvin makes up his mind to visit him and hopefully make amends before he dies. Because Alvin's legs and eyes are too impaired for him to receive a driver's license, he hitches a trailer to his recently purchased thirty-year-old John Deere 110 Lawn Tractor, which has a maximum speed of about 5 miles per hour (2.2 m/s; 8.0 km/h), and sets off on the 240-mile (390 km) journey from Laurens, Iowa, to Mount Zion, Wisconsin.

The Straight Story was released by Walt Disney Pictures in the United States. The film grossed $6.2 million in a limited theatrical release in the United States and sold 516,597 tickets nationwide during France's theatrical release. The film was a critical success, reviewers praised the intensity of the character performances, particularly the realistic dialogue which film critic Roger Ebert compared to the works of Ernest Hemingway. It received a nomination for the Palme d'Or at the 1999 Cannes Film Festival and Farnsworth received a nomination for the Academy Award for Best Actor.
