This study aims to provide legal certainty to consumers by highlighting consumer protection laws and the role of the government in protecting people who make transactions in e-commerce. This article is juridical-normative research. This article uses qualitative data that is a literature study. In this case, two types of data are used: primary and secondary data. Primary data includes Law Number 8 of 1999 concerning Consumer Protection. At the same time, secondary data is obtained from library sources such as books, scientific articles, theses, dissertations, research reports, internet websites, and other data sources. Miles et al. used the qualitative data analysis technique, namely data condensation, data presentation, and concluding.
