No - like all prokaryotes, bacteria do not contain organelles.
An organelle is defined as a compartment separated from the rest of the cell via a phospholipid membrane - including a nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus.
Bacteria have an outer plasma membrane (like all cells), but their intracellular contents are all freely diffusable. The only distinguishment made in bacteria is what is called the nucleoid, which is not a nucleus (i.e. not surrounded by a biphospholipid membrane), but simply condensed DNA that is still free within the cell.
Ribosomes are not organelles - they are macromolecules composed of ribosomal RNA (i.e. rRNA) and proteins which are responsible for protein synthesis (i.e. translation).
