One of the most critical aspects of an effective language learner, according to studies, is the adoption of efficient language learning strategies. As the outbreak of the Coronavirus 19 (COVID-19) pandemic has created alterations to the educational sector in which, including the Online Distance Learning (ODL) has become pivotal. On the other hand, suitable language learning strategies should be accessible and accommodating to all learners. Therefore, it is essential to ensure students' English language mastery in any educational environment. This study aimed to identify the most frequent Language Learning Strategies (LLS) utilised by undergraduate learners of English as a second language and to study the factors of specific LLS preferred by the learners during the ODL in the pandemic of Covid-19. This research incorporated a mixed-method design by employing both quantitative and qualitative methods. The research instrument for the quantitative approach is the online questionnaire namely Strategy of Inventory Language Learning (SILL) version 7.0 was adopted and adapted from Oxford (1989). The questionnaire was distributed using a purposive sampling to 78 respondents at a public university in Malaysia namely University Kebangsaan Malaysia (UKM). The second research instrument is semi-structured interviews conducted with 10 participants. Quantitative data was analysed and presented in a descriptive analysis to identify the most frequent LLS used by the participants. Moreover, the qualitative data was scrutinised and coded using thematic analysis. The quantitative results indicated a high preference for social strategies followed by metacognitive, compensation, cognitive, memory, and affective strategies. Thematic analysis for the qualitative method revealed that the social strategies utilised by the students were influenced by achievement goal-oriented, and a learning environment.
