Marriage Portrait of Isaac Massa and Beatrix van der Laen is a painting by the Dutch Golden Age painter Frans Hals, painted c. 1622 and now in the Rijksmuseum, Amsterdam.

The couple has been identified as Isaac Massa and his bride Beatrix van der Laen.

The painting shows a happy couple sitting against a tree "picnic-style", with a garden scene in the distance.

Beside him to the right sits a woman, bending slightly forward, with her head turned three-quarters left.

She wears a black dress under a dark-purple gown, a ruff, a white cap threaded with a pink ribbon, and lace-trimmed wristbands.
