1981 was a year in the 20th century.
- Unknown date: George McFly bought clothes at Sears, which he still wore in 1985.[1]
- Unknown date: The 1982 DeLorean DMC-12 is first constructed and sold.
- Biff Tannen Jr. was born to Biff Tannen and an unknown woman.[2]
- In 1931, the Hill Valley Science Expo featured a diorama entitled Hill Valley of the Future, which depicted life in a suitably futuristic Courthouse Square in 1981. Marty McFly wished that the town had looked that good in the actual 1981.
- Had the Hill Valley Science Expo continued, Emmett Brown (who was banned for 50 years due to his Electrokinetic levitator crashing into Atlas House of Glass) would have been permitted to return as a contestant.
