This book constitutes the proceedings of the International Joint Conference on Rules and Reasoning, RuleML+RR 2019, held in Bolzano, Italy, during September 2019. This is the third conference of a new series, joining the efforts of two existing conference series, namely RuleML (International Web Rule Symposium) and RR (Web Reasoning and Rule Systems).

The 10 full research papers presented together with 5 short technical communications papers were carefully reviewed and selected from 26 submissions.
