The prophetic books are a division of the Christian Bible, grouping 18 books in the Old Testament. In terms of the Tanakh, it includes the Latter Prophets from the Nevi'im, with the addition of Lamentions (which in the Tanakh is one of the Five Megillot) and Daniel, both of which are included among the books of the Hebrew Ketuvim. Baruch is also part of the prophetic books, but isn't part of the Hebrew Bible, and is seen by Christians as deuterocanonical, for which reason it is excluded from Protestant Bibles.
The prophetic books are named as such because prophets are traditionally attributed as authors. These authors were active between 750 BC and 450 BC. The first six of the books are known as the major prophets, while the last 12 are known as the minor prophets. These names do not imply that the major prophets are more important than the minor prophets, but refer to the major prophetic books being much longer than the minor ones. In Judaism, the minor prophetic books are grouped together as a single book.
Note that the prophetic books are not the same as books that contain prophets. For example, the prophet Elijah appears in the First and Second Books of Kings, but these books are not part of the prophetic books.
