Star Trek fans love a good cameo, especially when the surprise guest isn’t a professional actor. In this roundup of ten obscure star guest stars, we’ll travel from the hardwood to the holodeck, from rock stages to royal courts, and meet the unlikely faces who briefly walked the decks of the Enterprise, Voyager, and beyond. Buckle up for a ten‑obscure‑star adventure that proves the final frontier welcomes anyone with a little fame and a lot of curiosity.
1 Stephen Hawking
When Data decides to fire up the holodeck for a high‑stakes poker night, he invites three of humanity’s brightest minds to join the table: Isaac Newton, Albert Einstein, and none other than Stephen Hawking. The legendary physicist appears as himself, making him the only real‑life scientist to play his own character in a Star Trek episode.
In season 4’s “Descent,” the Enterprise crew even names a shuttle after Hawking, cementing his cameo as an official piece of canon. This brief yet memorable appearance solidifies Hawking’s place among the most obscure yet iconic guest spots in Trek history.
2 Abdullah Bin Al‑Hussein
Prince Abdullah bin al‑Hussein, now the reigning monarch of Jordan, is a confessed Trekkie. During a 1996 visit to the Voyager set, a quick‑thinking U.S. advisor arranged for the prince to appear as a background lieutenant‑science officer in the episode “Investigations.”
He exchanges a few silent words with Ensign Harry Kim, though his dialogue is inaudible due to non‑SAG‑AFTRA status. After filming, Dr. The Doctor (Robert Picardo) gifted him an autographed crew photo, and Prince Abdullah celebrated by throwing a party for the cast and crew—making him the sole real‑life royalty ever to pop up on a Star Trek series.
3 Mae Jemison
Mae Carol Jemison, the first African‑American woman to travel to space, also earned the distinction of being the first actual astronaut to step onto a Star Trek set. A lifelong fan inspired by Nichelle Nichols’ Uhura, Jemison was invited by LeVar Burton to appear in the TNG episode “Second Chances.”
She delivers a couple of lines while the episode focuses on Commander Riker’s transporter duplicate, Thomas Riker. Though her acting résumé is brief, Jemison’s cameo endures as one of the most obscure yet historically significant guest appearances in the franchise.
4 Stacey Abrams
Politics and Star Trek have always intertwined, and former Georgia gubernatorial candidate Stacey Abrams brings that blend to life in Discovery. In season 4’s “Coming Home,” she portrays the Federation President—an amalgam of Human, Bajoran, and Cardassian heritage—delivering a calm, authoritative presence that reflects her real‑world experience.
Although her screen time is limited to a few lines, Abrams’ portrayal of “Madame President” makes her the only sitting elected official to appear in a Trek drama, underscoring the series’ commitment to diversity and representation.
5 Melvin Belli
Known as the “King of Torts,” courtroom legend Melvin Belli stepped away from the bench and onto the bridge of the original series in the episode “And the Children Will Lead.” He plays Gorgan, a malevolent entity released by an archaeological dig, embodying an ancient race of space‑warring marauders.
Belli even convinced the studio to let his son, Caesar, appear as one of the children in the episode, making this perhaps the sole instance of a career lawyer acting in Star Trek history.
6 Jeff Bezos
Amazon founder Jeff Bezos has a surprisingly personal connection to Star Trek. After launching William Shatner into space aboard a Blue Origin rocket in 2021, Bezos had already slipped into the franchise a few years earlier.
In the 2016 film “Star Trek Beyond,” he dons full prosthetic makeup to portray an alien Starfleet officer stationed at Yorktown Starbase. His eight‑second cameo sees him advise a rescued crew member to “speak normally” before the scene cuts to Chris Pine’s Kirk, marking a brief but noteworthy appearance.
7 Mick Fleetwood
Drummer Mick Fleetwood of Fleetwood Mac fame traded drumsticks for a prosthetic suit in the TNG episode “Manhunt.” Cast as an Antedean ambassador—a tall, fish‑like species—Fleetwood’s towering frame made him an ideal fit for the alien role.
He has no spoken lines, and the part remained largely unnoticed for years, yet Fleetwood’s cameo stands as an early example of a rock legend quietly contributing to the golden age of Star Trek.
8 Iggy Pop
Deep Space Nine’s beloved episode “The Magnificent Ferengi” features punk icon Iggy Pop as the Vorta named Yelgrun. Initially, series producer Ira Steven Behr tried to secure Pop for a season‑3 time‑travel story, but scheduling conflicts delayed the collaboration.
Three years later, Pop finally appeared, nursing a wounded arm—sustained from a stage‑diving mishap the night before filming—while delivering a memorable performance that added a rock‑and‑roll edge to the Ferengi‑centric plot.
9 Tom Morello
Rage Against the Machine guitarist Tom Morello made his own trek onto the USS Voyager set in the episode “Good Shepherd.” As Crewman Mitchell, Morello guides a lost Captain Janeway through deck 15, offering directions with a quick‑witted exchange.
Although Mitchell never reappears, Morello’s brief interaction showcases how a celebrated musician can seamlessly blend into the universe’s fabric, leaving fans hopeful for future cameo cameos.
10 James Worthy
NBA Hall‑of‑Famer James Worthy, famed for his time with the Los Angeles Lakers alongside Magic Johnson, stepped into the Star Trek world as a towering Klingon named Koral in “Gambit, Part II.” Standing at an impressive 6‑foot‑9, Worthy’s presence made him arguably the most intimidating Klingon ever seen on screen.
In the episode’s climactic rescue, Koral’s silent, menacing stare does the heavy lifting, proving that a former basketball star can command a star‑fleet crew’s respect without uttering a single word.
