Havannah is an abstract strategy board game invented by Christian Freeling. It is played on a hexagonal board consisting of hexagonal spaces; a common size is eight hexes to a side (169 total), but ten hexes to a side is common at higher levels of play. Havannah belongs to the family of games commonly called connection games; its relatives include Hex and TwixT.

One player plays as Black; the other plays as White. Either may start, but the pie rule is commonly used to keep the first player from having a great advantage. The rules are as follows:

Each player places one stone of their colour on the board per turn; play then passes to their opponent. 
Stones are never moved, captured, or otherwise changed. 
A player wins when they complete one of three different structures from unbroken lines, or paths, of connected stones, all of their colour: 
A ring, which is a loop around one or more points (occupied or empty); 
A bridge, which connects any two of the six corners of the board; or 
A fork, which connects any three edges of the board; corner points are not considered parts of an edge. 
An example of all three winning combinations is shown at right. The structure in the centre of the board is a ring; the structure on the left-hand side is a fork; the structure on the right-hand side is a bridge.

While draws are technically possible, in practice they are extremely rare.

The game was published for a period of time in Germany by Ravensburger.
