Peptides (from the Greek πεπτος, "digestible"), are the family of short molecules formed from the linking, in a defined order, of various α-amino acids. The link between one amino acid residue and the next is an amide bond, and is sometimes referred to as a peptide bond.
Proteins are polypeptide molecules. The distinction is that peptides are short and proteins are long. There are several different conventions to determine these, all of which have flaws.
One convention is that those peptide chains that are short enough to be made synthetically from the constituent amino acids are called peptides rather than proteins. However with the advent of better synthetic techniques, peptides as long as hundreds of amino acids can be made, including full proteins like ubiquitin. Native chemical ligation has given access to even longer proteins, and so this convention seems to be outdated.
