SS Oregon

From Memory Alpha, the free Star Trek reference.

The SS Oregon was a 24th century starship registered for Federation travel.

Under the command of Captain W. Clinton, this vessel visited Dytallix in 2370. From there, it was due to arrive at Deep Space 9 on stardate 47567.2. (DS9: "Whispers")

The Oregon was never mentioned or shown, it was simply listed in an okudagram graphic of an arrival roster on a viewscreen. The graphic was also populated by some other in-jokes.

Presumably named for the US state.
