Leif Bruno Axmyr (11 June 1938 – 11 October 2018) was a Swedish convicted criminal.
At the time of his release in 2016, he had been imprisoned longer than any other Swedish inmate who had served a life sentence.
In May 1982, Axmyr was on leave from prison when he killed his ex-girlfriend and her male friend.
He was sentenced to life imprisonment for the double murder and other offences.
In 1997, the newspaper Svenska Dagbladet stated that Axmyr was Sweden's longest-serving prisoner in a Swedish prison.
Örebro district court commuted his life sentence to 51 years in 2013; he was released on 2 June 2016 after serving 34 years in prison (two thirds of his sentence).
