Back rank mate
A back rank mate is a checkmate on a player's first or eighth rank, typically by a rook or queen, delivered when the king's own pawns leave it no square to step to.
Castle, move no pawns, and your king lives happily on the back rank behind three of them. That is the very setup this mate punishes. A rook or queen lands on the rank with check, the king cannot step forward because its pawns are in the way, and nothing can take the checker or block.
The attack usually needs one more step. A defender must be removed, overloaded, or lured away so the rook can land safely. Look for a rook on an open file whose entry square is protected by only a single piece; trade it, deflect it, or sacrifice something to it and the mate appears. A queen sacrifice that pulls the last guard off the rank is a familiar way to finish.
You also get a free defensive lesson from it. Make luft early by pushing a rook pawn or a knight pawn, so the king has an escape square, or keep a rook or minor piece on the back rank that covers the entry square. Because kings castle so often, this pattern turns up in every phase of the game.
In the diagram it is Black's move and the rook plays Re1#. The white king on g1 is boxed in by its own pawns on f2, g2 and h2, nothing can capture the rook on e1, and no piece can block the check.
Also worth reading is Damiano's mate. Damiano's mate is a checkmate in which a queen gives check on h7 next to a king on g8, guarded by a pawn on g6, while the king's own pieces block its remaining flight squares.
A neighboring idea is Epaulette mate. An epaulette mate is a checkmate in which a queen checks a king whose two side squares are occupied by its own pieces, usually rooks, so it cannot step sideways.
Compare it with Hook mate. A hook mate is a checkmate in which a rook gives check next to the king, a knight guards the rook, a pawn guards the knight, and one of the defender's own pawns blocks the last flight square.
