A Wooded Marsh (c. 1660s) is an oil on canvas painting by the Dutch landscape painter Jacob van Ruisdael.

It is an example of Dutch Golden Age painting and is now in the collection of the Hermitage Museum in St. Petersburg, Russia.

A stagnant pool, overgrown with flowering water-lilies and other plants, extends from the centre of the distance to the foreground.

In the right foreground is a great withered oak; in front of it lies a felled beech, with the left end in the water.

[1] This scene is very similar to other paintings Ruisdael made in this period and these often served as inspiration for later painters of landscape.
