This is the proceedings of the 1st international workshop in Web personalisation, recommender systems and intelligent user interfaces (WPRSIUI), held in conjunction with ICETE 2005. This workshop is an opportunity for researchers and practitioners to exchange ideas about past, present and future trends in Web personalisation, Recommender systems and Intelligent user Interfaces. The workshop received 40 papers from 30 different countries of which 18 were accepted. Each paper was reviewed by two members of the program committee, who are experts in their field. I would like to thank the authors who contributed to this workshop, the invited speaker Professor Barry Smyth for agreeing to participate in the workshop and the programme committee for offering their expert reviewing. I would also like to thank the ICETE organising committee for their assistance and support during the organization of this workshop.
