Lyhytaaltoradioyhteisö refers to the community of individuals and organizations that use shortwave radio frequencies for communication. Shortwave radio operates in the high-frequency (HF) band, typically between 3 and 30 megahertz. These frequencies allow radio waves to travel long distances, bouncing off the ionosphere, which makes them suitable for international broadcasting, amateur radio communication, and various other specialized uses.

The shortwave radio community is diverse, encompassing amateur radio operators (hams), shortwave listeners (SWLs), professional broadcasters, and government agencies. Amateur radio operators use shortwave for personal communication, emergency preparedness, and participating in radio contests. Shortwave listeners tune in to broadcasts from around the world, enjoying news, cultural programs, and music from distant stations. International broadcasters, historically a significant part of the shortwave landscape, transmit programs in numerous languages to reach global audiences.

Despite the rise of the internet and digital communication, the shortwave radio community remains active. It offers a unique medium for reaching areas with limited internet access, for resilient communication during disasters, and for fostering a sense of global connection. The technology is relatively accessible, with entry-level equipment available for both transmitting and receiving. Many enthusiasts engage in technical discussions, equipment modification, and sharing reception reports. The community often organizes events and meetups, both online and in person, to share knowledge and experiences.
