Provided is a removable water-dispersible acrylic pressure-sensitive adhesive composition with which it is possible to form a pressure-sensitive adhesive layer that has excellent antistatic properties, adhesive properties, removability, removal stability, and the ability to prevent an increase in adhesive strength over time, less-staining properties on adherends, especially, the ability to prevent white staining on adherends in a high-humidity environment (the ability to prevent white staining), and appearance properties. The present invention is directed to a removable water-dispersible acrylic pressure-sensitive adhesive composition, including: an acrylic emulsion polymer including 70 to 99.5% by weight of a monomer unit derived from an alkyl(meth)acrylate and 0.5 to 10% by weight of a monomer unit derived from a carboxyl group-containing unsaturated monomer; an ionic compound; and a polyether antifoamer represented by formula (I) below. HO—(PO)n1-(EO)m1—H (I) In formula (I), PO represents an oxypropylene group, EO represents an oxyethylene group, m1 represents an integer of 0 to 40, n1 represents an integer of 1 or more, and EO and PO are added in a random form or a block form.
