"Investigation" (捜査) is a name given to several musical tracks in the Ace Attorney series. Each game has multiple "Investigation" themes that play during the investigation sections of gameplay.

In addition to the above, Ace Attorney Investigations: Miles Edgeworth and Gyakuten Kenji 2 also have tracks using the prefix "Deduction" (i.e., "Deduction ~ Contradiction at the Crime Scene" (推理 ~現場のムジュン) and "Deduction ~ Truth about the Crime Scene" (推理 ~現場の真実), respectively) that serve a similar purpose to the "Investigation" tracks.
