Swedish green marble, or simply Swedish green, is a marble from quarries in Kolmården, in the north-eastern part of the province of Östergötland in Sweden. It is fine-grained, with a variable green colour and attractive veining, due to serpentines in the stone. It is considered one of the hardest marbles in the world.^[1]

Swedish green has been used extensively in buildings and monuments in Sweden and abroad.
