Terpenoids are the largest and diverse family of natural secondary metabolites that have attracted more attention from chemists and pharmacologists for their intriguing skeletons and broad biological activities, including anti-inflammatory, antitumoral, antimicrobial, and anti-viral effects. Based on the previous reviews, we did a comprehensive summary of recent advances of bioactive terpenoids, focusing on their intriguing structural features and promising biological activities, covering the literatures from 2020 to 2023. In this review, 543 terpenoids with remarkable chemical architectures and biological properties are classified as monoterpenoids (7), sesquiterpenoids (142), diterpenoids (129), sesterterpenoids (24), triterpenoids (52), meroterpenoids (167), and miscellaneous terpenoids (14), that were isolated from terrestrial and marine resources. This review would provide a reference for researchers to rapidly discover the interesting terpenoids for further study as promising drug leads
