: A documentary included in home media releases is titled Return to Jurassic Park: The Third Adventure , which is sometimes mistaken for a subtitle.

Unlike its predecessor, The Lost World: Jurassic Park , does not have an official subtitle . It is the only film in the original trilogy and the wider Jurassic franchise (including Jurassic World: Fallen Kingdom and Dominion ) to use only a numeral.

However, early development and marketing materials did feature potential subtitles and taglines:

: During early script phases, when the story involved dinosaurs reaching the mainland, the working titles Extinction and Breakout were considered but ultimately discarded when the plot shifted back to the island.

: The film was marketed with the prominent taglines " Something Unexpected Has Evolved " and " Evolution of Adventure! ".
