Ketron is an Italian manufacturer of arranger keyboards, sound modules, and digital accordions, based in Ancona, Italy. Founded in 1981, the company began with a portable organ before pivoting toward digital technology, and from the early 1980s it collaborated with the German brand Solton — many products from that era carried "Solton by Ketron" branding, with Ketron handling the keyboard and arranger engineering side of the partnership.

The company is best known for its long-running line of professional arranger workstations aimed at solo entertainers, gigging keyboardists, and accordionists. Flagship instruments include the EVENT series (EVENT, EVENT 61, EVENT CHROM), the GLOBE, the FUSION, and the SD series of arranger keyboards (SD 1, SD 3, SD 5, SD 7, SD 9), alongside sound modules such as the EVM, EVM Plus, EVS, and EVENT X. Ketron also produces digital accordions like the P37 piano-type and B46 button-type, plus amplification gear and downloadable style/sound libraries.

Within the arranger-keyboard niche, Ketron has built a reputation for sophisticated style architecture, audio drum integration, and realistic acoustic instrument emulation — characteristics that have made its instruments a staple among one-man-band performers in Europe and beyond. The brand operates from Via Giuseppe Taliercio in Ancona and distributes internationally through dealers including Ketron UK.

Ketron has 5 products cataloged on Equipboard, including Sound Modules, Portable & Arranger Keyboards, and MIDI Foot Controllers. Their gear is featured by 1 artist, with the strongest followings in Rock and Metal. Notable users include Alan St. Jon.
