Johannes (Hans) Linthorst Homan (17 February 1903 – 6 November 1986) was a Dutch politician and diplomat.
During the German occupation, he sought to resign his position in September 1940, but had to remain in post until August 1941.
He had been a co-founder of the Dutch Union in 1940, before it was closed in favour of the Nationaal-Socialistische Beweging in 1941.
Following the war, he was prevented from continuing in his previous post, but took up other public positions including being chairman of the Dutch Olympic Committee.
He contributed to the failed Beyen plan and then participated in the Messina conference, leading the Dutch delegation which ended up with his signature of the Treaty of Rome.
