"Pyoco Pyoco Ultra" (ピョコピョコウルトラ^?, Pyokopyoko urutora, "Bouncy Bouncy Ultra" or "Peep Peep Ultra") is the 48th single by the Japanese female idol group Morning Musume, released in Japan on January 25, 2012 on the Zetima label.

It is the first single to feature 10th generation members (Haruna Iikubo, Ayumi Ishida, Masaki Sato and Haruka Kudo). It is also the first single since Takahashi Ai's graduation from the group, and the first single with Risa Niigaki as leader.

The single was originally supposed to be released on December 21, 2011, but was delayed to January 25 2012.

"Pyoco Pyoco Ultra" is the opening song for the Nippon Television series Sūgaku Joshi Gakuen, starring many Hello! Project members (the closing theme being "Hatsukoi Cider" by Buono!).

The single was released in four versions: a regular CD-only edition (catalog number EPCE-5842) and three limited editions, containing a bonus DVD.

As usual for Hello! Project CD singles, there also was a Single V (a DVD single, containing a music video for the title song) published. It appeared a week later, on February 1, 2012.

All songs written and composed by Tsunku.
"Pyoco Pyoco Ultra" arranged by Shōichirō Hirata.
