**Abstract:** Secondary metabolites from marine organisms are diverse in structure and function. Marine *Aspergillus* is an important source of bioactive natural products. We reviewed the structures and antimicrobial activities of compounds isolated from different marine *Aspergillus* over the past two years (January 2021–March 2023). Ninety-eight compounds derived from *Aspergillus* species were described. The chemical diversity and antimicrobial activities of these metabolites will provide a large number of promising lead compounds for the development of antimicrobial agents.

**Keywords:** marine *Aspergillus*; secondary metabolites; antimicrobial activity
