WDIO-DT (channel 10) is a television station in Duluth, Minnesota, United States, affiliated with ABC and owned by Hubbard Broadcasting. The station's studios and transmitter are located on Observation Road in Duluth.

WIRT-DT (channel 13) in Hibbing, Minnesota, operates as a full-time satellite of WDIO; this station's transmitter is located at Maple Hill Park south of Hibbing. WIRT covers areas of Minnesota's Iron Range (including Grand Rapids, Virginia and Chisholm) that receive a marginal to non-existent over-the-air signal from WDIO, although there is significant overlap between the two stations' contours otherwise. WIRT is a straight simulcast of WDIO; on-air references to WIRT are limited to Federal Communications Commission (FCC)-mandated hourly station identifications during newscasts and other programming. Aside from the transmitter, WIRT does not maintain any physical presence locally in Hibbing.
