In the title compound, C(11)H(10)ClNO(3), the mol-ecule consists of a benzene ring and an acetamido-acrylic acid unit on opposite sides of the C=C double bond. In the crystal, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds assemble the mol-ecules into infinite two-dimensional ribbons. These ribbons are linked into a network by inter-molecular C-H⋯π contacts.
