RTÉjr is an Irish free-to-air children's television channel operated by state-owned broadcaster RTÉ.

RTÉjr was initially a programming block on public service broadcaster RTÉ2, launching on 20 September 2010, replacing Den Tots.

[3] On 3 May 2011,[4][5] RTÉjr (which was only a programming block at that time) broadcast Punky, the world's first animated series which focuses on the life and adventures of a girl with Down syndrome.

By April 2013, the channel began a stand-alone schedule; however, plans to replace the RTÉjr block on RTÉ2 have yet to come to light.

Its flagship programme is hosted by former Six member Emma O'Driscoll, Muireann NiChiobhain, Clara Murray and their puppet friends Séamus the dog and Bláithín the flower fairy.
