Per "Pelle" Lindström (9 April 1936 – 21 August 2009, Gothenburg) was a Swedish logician, after whom Lindström's theorem and the Lindström quantifier are named. (He also independently discovered Ehrenfeucht–Fraïssé games.) He was one of the key followers of Lars Svenonius.
A festschrift for Lindström was published in 1986.
