Jan Józef Lipski (26 May 1926 in Warsaw – 10 September 1991 in Kraków) was a Polish critic, literature historian, politician and freemason.

Between 1956 and 1957 Lipski was an editor of the pro-reform weekly "Po prostu"; from 1957 to 1959 he was president of the Crooked Circle Club.

As the only senior member of the non-communist opposition, he re-established the Polish Socialist Party (Polska Partia Socjalistyczna), which he led from 1987.

In 1989 he was elected Senator from Radom and was a member of the Civic Parliamentary Club (Obywatelski Klub Parlamentarny); he died during his term in office.

For acts during the uprising, Lipski was decorated with the Cross of Valour (Krzyż Walecznych) ("for lifetime achievement, for the brave stance in the street fighting of 25 September, for persevering in a shed at the police station giving a small fire under a strong defence, where he was wounded, and for active participation in patrols"), posthumously awarded the Grand Cross of the Order of Polonia Restituta (by Polish President Lech Walesa on 13 September 1991) and with the highest Polish decoration, the Order of the White Eagle (by President Lech Kaczynski, 23 September 2006).
