|The king's movement may be hindered by other pieces. Black's king cannot move to squares under attack by the white bishop, knight, queen, or pawn; White's king cannot move to squares under attack by the black queen.

The white king starts on e1, on the first {{chessgloss|file}} to the right of the [[Queen (chess)|queen]] from White's perspective. The black king starts on e8, directly across from the white king. Each king starts on a square opposite its own color.

A king can move one square horizontally, vertically, and diagonally unless the square is already occupied by a friendly piece or the move would place the king in check. If the square is occupied by an undefended enemy piece, the king may capture it, removing it from play. Opposing kings may never occupy adjacent squares (see [[opposition (chess)|opposition]]) to give check, as that would put the moving king in check as well. The king can give [[discovered check]], however, by unblocking a [[Bishop (chess)|bishop]], [[Rook (chess)|rook]], or queen.

The king can make a special move, in conjunction with a rook of the same color, called ''castling''. When castling, the king moves two squares horizontally toward one of its rooks, and that rook is placed on the square over which the king crossed.

Castling is permissible under the following conditions:
* Neither the king nor the castling rook have previously moved.
* No squares between the two pieces are occupied.
* The king is not in check.
* None of the squares the king would move across or to are under enemy attack.

Castling with the h-file rook is known as ''castling kingside'' or ''short castling'' (denoted 0-0 in [[Algebraic notation (chess)|algebraic notation]]), while castling with the a-file rook is known as ''castling queenside'' or ''long castling'' (denoted 0-0-0).
