Oppland [ˈɔ̂plɑn] (listen) was until 1 January 2020 a county in Norway bordering to the counties of Trøndelag, Møre og Romsdal, Sogn og Fjordane, Buskerud, Akershus, Oslo and Hedmark. The county administration was located in Lillehammer.
Oppland was, together with Hedmark, one of the only two landlocked counties of Norway. Oppland and Hedmark counties were merged on 1 January 2020 to become the new county Innlandet.
Innlandet was one of several names proposed for the new administrative region consisting of Hedmark and Oppland. The two counties were re-merged after being split in 1781 (then called Hedemarkens amt and Kristians amt, respectively). Historically, the region was commonly known as "Opplandene".
