흥미(興味)는 물체, 사건, 과정 등에 이끌리는 정서나 감정으로, 어떤 것에 대하여 관심을 가지게 되는 것을 말한다. 흥미가 있는 것을 직업이나 취미로 가지게 된다면 삶의 만족도가 올라간다. 현대에서 이야기되는 심리학적 흥미의 경우, 호기심, 그리고 훨씬 더 적은 수준의 놀라움과 같은 기타 더 심리학적인 용어를 아우를 수 있는 포괄적인 개념으로 사용된다.
↑The following can be read in a review or blurb concerning Paul Silvia's Exploring the Psychology of interest: "Anyone interested in emotions will find this book on the emotion of interest immensely interesting! If you are among those who question the status of interest as an emotion, this book will convince you. This very real emotion not only exists, but also plays a major role in shaping our lives. This book goes a long way toward documenting what I have long believed. Of all the emotions, interest has the greatest long-term impact across the life span."--Carroll E. Izard, PhD, Trustees Distinguished Professor, Department of Psychology, University of Delaware
