ICLP2001 was the 17th International Conference on Logic Programming andcontinuedaseriesofconferencesinitiatedinMarseille, France, in1982.This year ICLP was held in conjunction with CP2001, the 7th International C- ference on Principle and Practice of Constraint Programming. A coordinated programscheduleandjointeventswereorganizedinordertomaximizethe- teractionbetweenthesetwoneighboringcommunities.LOPSTR2001, the11th international workshop on Logic-based Program Synthesis and Transformation was also co-located with ICLP2001 and CP2001 this year, bringing together a larger community to share novel research results. Seven satellite workshops were also associated to the conference and took place on the day following the conference. We received 64 papers, among which 23 were selected for presentation at theconferenceandinclusionintheconferenceproceedings.Inadditiontopaper presentations, theconferenceprogramalsoincludedfourinvitedtalksandfour tutorials.Wechosethisyeartocelebratethefoundersofthelogicprogramming ?eld, namelyAlainColmerauerandBobKowalski, whoarebothcelebratingtheir 60th birthday. The other two invited talks were given by Patrick Cousot, p- neerinthe'eldofabstractinterpretation, andAshishGupta, whopresentedhis industrial experience on cross-enterprise databases at amazon.com and Tavant Technologies. The four tutorials were given by Eric Villemonte de la Clergerie, V.S.Subrahmanian, KazunoriUeda, andJanWielemaker.
