This study presents a bibliometric analysis of research on 21st-century skills published between 2015 and 2025, sourced from the Scopus database. The analysis examines publication trends, geographic distributions, collaboration patterns, citation impacts, and thematic clusters to map the evolution of this critical educational domain. The data shows significant fluctuations in research output, influenced by global events such as the pandemic, emphasizing digital literacy and adaptive learning resurfacing postpandemic. Malaysia and Indonesia are gaining prominence, while the United States and the Netherlands remain dominant. This empirical research identifies three key clusters: pedagogical approaches, technological integration, and structural frameworks, with identified gaps in cultural adaptation and affective skills research. Collaboration networks reveal strong transcontinental partnerships, though imbalances persist in global knowledge production. The study highlights the field's maturity and responsiveness to educational disruptions and calls for including longitudinal and interdisciplinary studies. Affective skill development, cross-cultural studies, and equitable collaboration are recommended.
