An invasion (Japanese: uchikomi) is a play made inside an enemy framework with the intention of living or escaping.

See also Invasion Itinerary.
Invasions occur throughout the game.
- In the opening they are probably part of standardised joseki.
- In the middle game they may be middlegame joseki, follow-ups in well-known positions, or just as likely occur as one player exerts the power of influence built up in an earlier fight.
- In the endgame they can be considered as 'gouging' tactics (Japanese eguri).
The difference between the second and third cases is that invasions in the middle game phase may create weak groups; which have no place in the endgame, where everything in theory is already settled in status and there is nowhere much to run.
