The plot follows Woody, Buzz and the rest of the toys as they plan a romantic getaway for Mattel’s sweetheart couple, Ken and Barbie.
The move could help Toy Story steal back some of the limelight from Cars 2. Disney recently revealed that the Cars brand was on-course to overtake Toy Story at retail.
Merchandise for Cars 2 began to roll out in May and is already on track to meet retail projections that will exceed Toy Story 3's sales last year.
Pixar's chief creative officer, John Lasseter said: "We really believe in the short film. It just kind of keeps new animation of our favourite characters going."
Toy Story 3 was recently named the Best Licensed Programme at this years Licensing International Expo.
Cars 2 opens in cinemas on June 22nd.
