Sir Alex Ferguson: Never Give In is a 2021 British documentary film about the former Scotland, Aberdeen and Manchester United football manager Alex Ferguson.

The documentary recounts Ferguson's life from his early experiences in Govan, through his playing career as a striker at Rangers amongst others, to his long and successful managerial career, using archive footage and interviews with Ferguson that began in 2016, and includes Ferguson's recovery from his 2018 brain haemorrhage.

The documentary helped Ferguson end a long running feud with Gordon Strachan, his former player at Aberdeen and Manchester United, that had begun in the 1980s. The two went out for lunch and buried the hatchet at the urging of Ferguson's son Jason. Strachan appears as a talking head in the film along with 11 other interviewees in total: Ferguson, five family members (Ferguson's wife Cathy Ferguson and their sons, Jason, Mark and Darren along with his brother, Martin Ferguson), two doctors, and Ryan Giggs, Eric Cantona and Archie Knox.
