Once Niñas y Niños (Eleven Girls and Boys) is a Mexican children's television network owned by the Instituto Politécnico Nacional.

Once Niñas y Niños is broadcast as a subchannel on the IPN's Canal Once transmitters and is a required channel for carriage on all pay television systems in Mexico;[1] it also airs a programming block of children's programs on the main Canal Once channel.

[2] The channel would serve as an extension of the main channel's original children's programming for children between the ages of four and twelve; overnight, between midnight and 6am, it would not air programming, but instead an image inviting kids to go to sleep.

[2] The name was modified from Once Niños to Once Niñas y Niños on January 15, 2020, as part of an initiative to promote gender parity; the name in Spanish had previously read Eleven Boys.

It is also available as a subchannel of XHZHZ-TDT, the state-owned television station in the state of Zacatecas.
