Orgelbau Graf is a Swiss organ-building company based in Sursee, in the canton of Lucerne. The company was founded in 1950 by Walter Graf, who moved the headquarters to new premises in Oberkirch, Lucerne, in 1960. Graf learned organ building at Orgelbau Willisau AG. In 1987, the workshop was handed over to his son, Walter II Graf, who passed away unexpectedly a year later.

In 1988, employees Rudolf Wyss and Othmar Najer took over the business and converted it into a joint-stock company in 1992. From 2013, Wyss continued as the managing director until his retirement, after which Jens Krug and Evelyn Kaufmann took over. The company's catalog includes over 200 works throughout Switzerland.
