Jonathan Del Arco (born 7 March 1966; age 54) is the Uruguayan-born actor who played Hugh, the Borg drone with a sense of individuality, in the Star Trek: The Next Generation fifth and seventh season episodes "I Borg" and "Descent, Part II". He reprised the role in the Star Trek: Picard first season episodes "The End is the Beginning", "The Impossible Box", and "Nepenthe".
He also appeared as Fantome in the Star Trek: Voyager episode "The Void". Footage from his appearance in "I Borg" was also used in the TNG sixth season episode "Descent".

He was interviewed on 14 February 2002 for the TNG Season 5 DVD special features "Mission Overview Year Five" ("I Borg") and "Intergalactic Guest Stars" ("Profile: "Hugh" Borg"). According to the latter interview, Del Arco auditioned for the part of Wesley Crusher at the beginning of The Next Generation.
Del Arco also supplied his voice to two Star Trek video games: Star Trek: Armada II, for which he provided additional background voices, and Star Trek: Bridge Commander, for which he voiced the character of Miguel Pedro Diaz.
Del Arco made his television debut in a 1987 episode of Miami Vice, working with Rosana DeSoto. He then made his feature film debut in the drama Lost Angels, which also featured Keone Young.
