This study was conducted to investigate student barriers to the prospect of online learning in Vietnam, in the context of Covid-19 pandemic. This mixed-method study attracted the participation of 1165 students from twelve universities and nine high schools across thirteen provinces in the Mekong Delta. The findings revealed the additional three obstacles from the qualitative data analysis including (1) geographical features, (2) the economic status of Vietnamese people, and (3) Vietnamese culture and traditions in addition to the six groups of barriers being re-confirmed from Berge's framework (2005). The results of Binary Logistic Regression testified the negative impacts of obstacles in Learner Motivation, Cost and Access to the Internet, and Social Interaction on the prospects of online learning, though it is predicted to go farther in education in Vietnam in the future.
