This volume is the proceedings of the 6th International Workshop on Bidirectional Transformations (BX 2017). Bidirectional transformations (BX) are a mechanism for maintaining the consistency of at least two related sources of information. Such sources can be relational databases, software models and code, or any other document following standard or ad-hoc formats. BX are an emerging topic in a wide range of research areas, with prominent presence at top conferences in several different fields (namely databases, programming languages, software engineering, and graph transformation), but with results in one field often getting limited exposure in the others. BX 2017 was organized as a dedicated venue for BX in all relevant fields, as part of a workshop series that was created in order to promote cross-disciplinary research and awareness in the area. As such, since its beginning in 2012, the workshop has rotated between venues in different fields. In 2017, BX will be co-located with ETAPS in Uppsala, Sweden; it was previously held at the following locations: The call for papers attracted 10 complete submissions plus 2 talk proposals, from which the programme committee, after a careful reviewing and discussion process, selected for presentation at the workshop 9 papers (5 regular, 1 tool and 2 short) and 2 talk proposals: In addition to these presentations, the programme of BX 2017 will include a panel for discussion. We hope that this discussion will lead to interesting submissions to next year's BX workshop, which will take place at a venue yet to be arranged. We would like to thank the Programme Committee and the external reviewers for their detailed reviews and careful consideration, and for the overall efficiency that enabled the tight schedule for reviewing. We would also like to thank all the authors and participants for helping us make BX 2017 a success.
