What are OpenOffice.org and LibreOffice?
OpenOffice.org (OOo) and LibreOffice (LO) are suites of programs for word processing, spreadsheets, presentations, databases, and drawings. They are free to download, use, and distribute. They are available in many languages and run on Linux, Mac, Windows, and (OOo) other operating systems. Their native file formats are OpenDocument (*.ODT, *.ODS, *.ODP, etc.), but they can open and save to many other formats, including Microsoft Office formats (*.DOC, *.XLS, *.PPT, etc.).
The programs are very similar, being based on the same code. A few features differ, so your choice might depend on your needs. For most people, there is no significant difference between the two programs. To get one, go to the OpenOffice.org website or the LibreOffice website. You can install both programs on the same computer and switch between them.
Good introductions are Introducing OpenOffice.org (PDF) and Introducing LibreOffice.
Note (December 2011): Future versions of OpenOffice.org will be produced under the name “Apache OpenOffice” (AOO).

Note: Some of the material on this site may be out of date. Some of it was originally written for OpenOffice.org 1.1.3 and has not been updated for OOo 2 or OOo 3. Some details have changed, but the general information is still relevant. I am updating the pages as I find time.
