Brødrene Hals was a piano manufacturer and publisher in Christiania (Oslo) from the 1890s. Karl Hals (1822–1898) and his brother Petter (1823–1871) originally founded the piano firm in the 1850s. Hals had its own concert hall from 1880, and moved into retail music sales and publishing with the purchase of Håkonsens Musikhandel in 1887. It merged with Norsk Musikforlag in 1909.
Brødrene Hals published many works by Agathe Backer-Grøndahl (1847—1907), Johan Backer-Lunde, Catharinus Elling, Christian Cappelen, Borghild Holmsen, Wilhelm Kloed, Johan Selmer and some by other better-known composers such as Ludvig Schytte (1848—1909), Karl Hals' son-in-law Ole Olsen (1850—1927), Christian Sinding (1856—1941) and Edvard Grieg (1843—1907).
