The Star Wars: Titanium Series toy line is a collection of die-cast Star Wars vehicles produced by Hasbro from 2005 to 2009. Most are small, but several vehicles were released in a larger scale. Also included in this collection is a set of 3.75-inch die-cast action figures with limited articulation. Later, a Titanium Series subset of the Star Wars: The Black Series toy line was released. The Titanium Series brand also included lines based off Hasbro's own Transformers series, as well as Universal Studios' Battlestar Galactica.
