An electronic portfolio (also known as a digital portfolio, online portfolio, e-portfolio, e-folio, or eFolio) is a collection of electronic evidence assembled and managed by a user, usually on the Web. Such electronic evidence may include input text, electronic files, images, multimedia, blog entries, and hyperlinks. E-portfolios are both demonstrations of the user's abilities and platforms for self-expression. If they are online, users can maintain them dynamically over time.

One can regard an e-portfolio as a type of learning record that provides actual evidence of achievement. Learning records are closely related to the learning plan, an emerging tool which individuals, teams, communities of interest, and organizations use to manage learning. To the extent that a personal learning environment captures and displays a learning record, it may also operate as an electronic portfolio.

E-portfolios, like traditional portfolios, can facilitate students' reflection on their own learning, leading to more awareness of learning strategies and needs.
