This volume contains the proceedings of the First International Workshop on Gender-Inclusive Translation Technologies (GITT-2023)1, hosted by the 24th Annual Conference of The European Association for Machine Translation (EAMT 2023). GITT is set out to focus on genderinclusive language in translation and cross-lingual scenarios. The workshop brings together researchers from diverse areas, including industry partners, MT practitioners and language professionals. Also, GITT aims to encourage multidisciplinary research that develops and interrogates both solutions and challenges for addressing bias and promoting gender inclusivity in MT and translation tools.
