This study aimed to investigate the interrelationship of psychological capital (PsyCap) and mindful learning for English learning engagement and the possible path from PsyCap to English learning engagement with mindful learning as the mediator for university students in Taiwan. Data from 245 Taiwanese university students were used to analyze their PsyCap, mindful learning, and English learning engagement. The results of structural equation modeling indicated that PsyCap predicted mindful learning, mindful learning predicted English learning engagement, and a complete mediation existed with mindful learning as the mediator between PsyCap and English learning engagement. The findings suggested that training and practicing PsyCap and mindful learning may be effective in facilitating English learning outcomes.
