Due to the prevalence of information and communication technologies (ICT) among secondary school students and the increasing significance of digital reading, exploring the impact of ICT on students’ digital reading performance in English seems necessary. The current research aimed to examine the effects of ICT competencies factors on secondary school students’ English digital reading performance. Data were obtained from 7703 15-year-old students from three East Asian economies, Macau, Hong Kong, and Singapore, from the Programme for International Student Assessment (PISA) 2018 dataset. The results of hierarchical regression analysis revealed that students’ ICT literacy was negatively correlated with their English digital reading performance, while the influence of attitudes toward ICT varied across the three East Asia economies. Additionally, males had lower English digital reading achievement, while students with higher socioeconomic status (SES) had higher English digital reading performance.
