A polyhydroxyalkanoate (PHA) water-based coating, a preparation method therefor, and a use thereof. The coating comprises a PHA suspension and an auxiliary agent, wherein the melting point of PHA is 100-120°C, and the PHA is a copolymer containing at least two polymerization monomers. By selecting the PHA meeting specific conditions, the obtained coating is environment-friendly and degradable, and the prepared coated paper can be directly pulped and recycled. The coated paper has good comprehensive performance in terms of stable standing, temperature resistance, oil resistance, environment friendliness, and coating flatness, and can meet the requirement for containing high-temperature liquids.
