on Plus is an American free linear television network owned by the Katz Broadcasting subsidiary of the E. W. Scripps Company that formerly operated as a broadcast television network until February 28, 2021. The network originally launched in 2007 as Ion Life, maintaining a format featuring lifestyle programming focused on health and wellness, cooking, home decor, and travel. With expanded cable carriage, in 2019, Ion Media converted the network into a general entertainment format that matched that of parent network Ion Television, featuring day-long marathons of various drama series.

Ion Plus was carried mainly as a digital multicast service on Ion Media Networks-owned stations as well as select Ion Television affiliates, usually to the third subchannel; its base national feed was also available on select cable and satellite providers. In select markets, Ion Plus has had main channel placement, allowing it must-carry coverage on local cable and satellite services.

Ion Plus ceased broadcasting over-the-air after Ion Media's acquisition by the E. W. Scripps Company and merger with Katz Broadcasting, but continues to air as an advertising-supported video-on-demand network through several AVOD streaming services, including Samsung TV Plus, and Vizio WatchFree.
