Lenco is a brand of audio and video equipment, originally used by the Swiss turntable manufacturer Lenco AG from the 1940s until the 1980s. The name is now owned by Dutch concern Commaxx International NV.

Lenco AG was founded in 1946 in Burgdorf, Switzerland by married couple Fritz Laeng and Marie Laeng-Stucki, with Bruno Grütter. In 1925 Fritz had set up and run Radio Laeng, a shop selling and renting radios in complete and kit form. The name Lenco was derived from their surname.

The firm initially produced a range of household products moulded in plastic and aluminium before launching its first turntable in 1949 to take advantage of the, then new, LP record format introduced by Columbia Records.

From the mid-1950s, Lenco supplied turntables for sale in other countries, initially under the name of a local commercial partner, including Bogen in the United States and Goldring in the United Kingdom, later under its own name.

In 1961 Lenco opened a factory in Osimo, Italy, where it initially produced electric motors. In the 1970s, the Italian factory started to produce turntables and cassette decks.

The company grew to export its products to over eighty countries around the world.

The mid-1970s downturn in the global economy depressed the demand for high fidelity audio equipment. Coupled with increasing competition from products made in the Far East, Lenco's fortunes declined. Lenco AG Burgdorf was declared bankrupt in 1977, as successor company Lenco Audio AG took over repair, service and warranty duties for existing Lenco equipment until it folded in 1983.

Marie Laeng died in 1974 and Fritz Laeng in 1978.
