4-chlorophenoxy acetic acid (4-CPA), a chlorine derivative of phenoxyacetic acid (PA), is a synthetic plant growth regulator.

It is an auxin-like plant growth regulator, absorbed by plant via root, stem, leaf, bloom and fruit. It is used to prevent abscission of bloom and fruit, inhibit rooting of beans, promote fruit set, induce formation of seedless fruit. Also used for ripening and fruit thinning. It performs better when used in combination with 0.1% monopotassium phosphate. It also has herbicidal effect at high dosage.

Has been shown to increase fruit size in tomatoes, moreso than other common plant growth regulators such as BA & GA4+7 (van Tonder & Combrink, 2003)
