Vanessa Lynn Branch is an English-born American actress and model. She is best known in the United States as the Orbit Gum girl for its 2002 to 2010 television marketing campaign, as well as Giselle in the Pirates of the Caribbean series, specifically Gore Verbinski's trilogy and James Ward Byrkit's short film Tales of the Code: Wedlocked.

Orbit is a brand of sugarless chewing gum from the Wrigley Company. In the United States, where it was re-launched in 2001, it is sold in cardboard boxes with 14 individually wrapped pieces per package. In the UK, where it was launched in 1899 it was originally sold as a traditional long-stick gum, later replaced by the same format as the US.
