Yo Gabba Gabba! is a children's musical television series created by Christian Jacobs and Scott Schultz and developed by Kay Wilson Stallings. The series is about five costumed toys come-to-life and their friend DJ Lance Rock (Lance Robertson). It is co-produced by the Magic Store and Wildbrain Entertainment. Its first episode premiered on Nickelodeon on August 20, 2007, as a part of its Nick Jr. block. Its original run ended on November 12, 2015.

A single topic is addressed in each episode (such as "Adventure", "Friends", or "Dance") through songs and short storylines. Additionally, the show teaches children life and social skills, such as sharing and trying different foods. It also encourages viewers to move along with and dance with the characters in the program. The show is noted for its indie-culture guest stars and bands, and for drawing visual inspiration from 8-bit video games and H.R. Pufnstuf, among other television shows. Created by Jacobs (lead singer of the Aquabats) and Schultz, the show's learning process has parents, older siblings, and younger children watch the show together rather than letting it act as a babysitter. The television program spawned a touring live stage show, several toys, and branded clothing.

For the first season, Jacobs and Schultz both served as writers and alternated as directors for each episode, with Bradley Zweig serving as the story editor for the entirety of the season. Before the second season, Zweig stepped down from his position as story editor to work as a writer for the first season of another Nickelodeon television series, The Fresh Beat Band (2009-13). Dan Clark was brought in to fill Zweig's position, and also served as a writer for that season, alongside Jacobs, Schultz, Matthew Fackrell, Jason deVilliers, Tiffany Campbell, Sarah Dyer, Evan Dorkin, and Jordan Kim. Fackrell and deVilliers also joined the directing staff for the second season.

The third season saw Jacobs, Schultz, Fackrell, deVilliers, Dyer, Dorkin, and Kim all return, joined by new writers Craig Windes, Joel Fox, Kevin Sukho Lee, and Jacobs' older brother Parker. Fox was also added to the directing staff. For the fourth and final season, the Jacobs brothers, Schultz, Fackrell, deVilliers, Kim, Windes, and Lee all stayed on, with Kim and Windes also added as directors, joined by several new writers, including brothers Matt and Mike Chapman, Sean Mortimer, Julia Vickerman, Christian and Parker's younger brother Tyler, Bryce Clark, Brent Johnson, Fackrell's brother Nathan, and series star Lance Robertson. The Chapmans, Vickerman, Tyler, Johnson, and Nathan also served as directors.

For the entirety of the show's run, Justin Lyon and Ritamarie Peruggi served as producers, with Peruggi also serving as supervising producer for several episodes. Michael Polis and Jon Berrett were executive producers of the series.

In 2021 it was announced that the series would be revived for Apple TV+. The revival series, titled Yo Gabba Gabbaland!, consists of 10 new episodes and premiered on August 9, 2024. Apple TV+ has also acquired the previous episodes and specials for its service.
