Adolf Østbye (February 1868 – September 5, 1907) was a Norwegian revue artist and barber who became the first person to make a recording in Norway.
Østbye's Norwegian recording sessions were held at the Grand Hotel, Kristiania.
Many of these sold very well, and the most popular title "Bal i Hallingdal" together with Carl Mathisen (September 25, 1870 Holmsbu, Norway – 1933 Ray, North Dakota, US) at accordion remained in the HMV catalogues until the late 1930s.
Østbye also began to start up his own record company, "Ekko - Kristiania" during 1906–07.
On several record labels, Østbye's last name has also been spelled: Östby(e), Østby(e) and Ostby(e).
