Loki/Tony Stark is a pairing in the Marvel Cinematic Universe. Loki appears in the Thor movies, Tony in the Iron Man movies, and they both appear in The Avengers (2012), Avengers: Infinity War (2018), and Avengers: Endgame (2019). The pairing is often based on the defenestration scene in The Avengers (2012), and/or on the assumption that they're both morally grey characters, liars, showmen and hedonists.
The earliest stories were written as a crossover of the Iron Man and Thor movies. Fic for the pairing was posted on AO3 as early as May, 2011.  “Frostiron 101” meta by kyrilu & chaperoned has a detailed history of the pairing.
