绘本（Picture Book），顾名思义就是「画出来的书」。整本书以图画为主，可以连贯成为单一完整故事的称为绘本。简单来说，只要把整本书的文字全部拿掉，读者光靠整本书的图还可以知道整本书的故事内容在说什么，才可以被称做为绘本。
A picture book, simply put, as long as the text of the entire book is removed, the reader can know what the story of the entire book is saying only by relying on the pictures of the entire book, and it can be called a picture book.
绘本常常被人以插图为主的故事书搞混。整本书若以文字为主，就算每一页都有插图，将整本书的文字拿掉后，若读者光看图看不出整个故事的来龙去脉，那就是故事书。绘本有分年龄层，儿童绘本主要是针对幼儿、儿童所设定的出版品，多以适合幼儿、儿童阅读的内容为取向，成人绘本则是以成人阅读的绘本为主。
在大学的科系中，绘本并没有自己的系或研究所。绘本都是被归类在幼教系，美术系或儿童文学研究所里面的选修或必修学分里。
Picture books are often confused by story books that are mainly illustrations. If the whole book is mainly written, even if there are illustrations on each page, after removing the entire text, if the reader can’t see the ins and outs of the whole story by looking at the pictures, it is a story book. Picture books are divided into age groups. Children’s picture books are mainly published for toddlers and children, and are mostly oriented to content suitable for toddlers and children to read. Adult picture books are mainly picture books read by adults.
Among the departments of the university, picture books do not have their own department or research institute. Picture books are classified as elective or compulsory credits in the Department of Early Childhood Education, Department of Fine Arts, or the Institute of Children’s Literature.
