Catharina Both van der Eem is a painting by the Dutch Golden Age painter Frans Hals, painted in 1620 and now in Louvre Museum.

Similar to Hals' Portrait of a Woman Standing in Chatsworth House, this woman is wearing a wedding ring on her right forefinger, a figure-eight collar and lace wrist collars with gold bracelets.

Her bodice is a richly embroidered Dutch wedding stomacher, and a heavy gold chain draped through a vlieger, rests on a wheel-shaped fardegalijn.

Her diadem cap lacks wings and is more similar to the cap worn by Hals's unknown sitter Portrait of a Woman Standing (Kassel) and by his brewer Aletta Hannemans.

Her left hand grasps her dress; her right rests on the back of a chair.

The style of painting, which is similar to that of the earliest groups of marksmen at Haarlem (431-3), makes the date 1620 probable.

[2]In 1974 Seymour Slive listed both paintings as pendants of each other and confirmed the Hals attribution, which had been called into question in 1970.

[3] Slive agreed with the traditional date of 1629 but felt that it could have been painted soon after the couple's marriage in 1619 as documented by E.A.

He agreed with Numa S. Trivas that it was painted by Hals and not as some claimed, by Pieter Soutman.
