'''''Ultra Q''''' (ウルトラQ or '''''Urutora Kyū''''') is a {{toku}}satsu [=SF/=]{{Kaiju}} series made in the tradition of Creator/{{Toho}}'s many tokusatsu sci-fi/horror films.

Produced in black and white by Tokyo Broadcasting System/Tsuburaya Productions, ''Ultra Q'' is actually the first of the long-running ''Franchise/UltraSeries'', and was broadcast on Tokyo Broadcasting System from January 2 to July 3, 1966 (the final episode was preempted until December 14, 1967), with a total of 28 episodes. This series was followed a week later by the more well-known ''Series/{{Ultraman}}'' (''Urutoraman'', 1966), the second ''Ultra'' Series.

Unlike most of the franchise it would spawn, it did not have a size-changing HenshinHero. Instead, it was more of a mystery-of-the-week format that gets it compared to ''Series/TheOuterLimits'' (even with an intro reminiscent of it!) with, of course, giant monsters being the culprit a lot more often than it was in those series.

!!''Ultra Q'' provides examples of the following tropes:

* EggMacGuffin: Litra's egg in the first episode, as Litra is the only thing capable of killing the monster Gomess, so they try to hatch the egg in the hopes that Litra will take care of the rampaging monster for them.
* FollowTheLeader
** Considered by western fans to be this to ''Series/TheOuterLimits'' or ''Series/TheTwilightZone'', but a better comparison is found in ''Franchise/{{Quatermass}}''. Which makes it funnier that the English dub was made by the producers of ''The Twilight Zone'', and acquired by the producers of ''The Outer Limits''.
** Also, it was the popularity of the ''Franchise/{{Godzilla}}'' franchise that led to the monsters taking center stage and the ''Franchise/UltraSeries'' that followed being all about heroes vs. monsters. Creator/EijiTsubaraya didn't want it to be this way at first, but was talked into including more monsters by ThePowersThatBe.
* InstrumentalThemeTune
* {{Kaiju}}: Plenty.
* OpeningNarration: "For the next 30 minutes, your eyes will leave your body and enter inside this fantasy time..."
* {{Theremin}}: The music and the theme had this and the musical saw.
