Dimension 4 – Docking Station was the debut concert tour of South Korean girl group f(x) launched in support of their fourth studio album, 4 Walls.

The tour was announced by SM Entertainment on October 28, 2015, more than 6 years after f(x)'s official debut in September 2009.

[1] On holding their first solo tour, the group stated the following: This is the first time we are having our own stage.

We are very excited and nervous, as this is the first stage that we’re meeting our fans exclusively, and we have a lot of performances that we have yet to show you.

The DVD and Blu-ray features their first Asia tour, visiting more than 6 venues for a total of 11 shows.
