Lord of the Rings RPG by Decipher, using the CODA system.
The One Ring RPG by Cubicle 7, with a custom system.
As described by TSR game editor John Rateliff here, TSR sought to acquire the Middle-earth license in 1992, and even produced a prototype cover mock-up, character creation rules, and character sheets. The game was planned to be an entry-level "D&D lite." But TSR execs turned the license down once the Tolkien Estate refused to allow TSR to write new novels set in Middle-earth(!). The Second Edition of MERP came instead.
Likewise, Rateliff says that in 2000, WotC negotiated for the license as the New Line films were coming out, and plans were made for a full standalone d20 game similar to WotC's Wheel of Time d20 game, yet the negotiations fell through due to either a fear of WotC being accused of monopolism in the TPRG market (!), or due to WotC's licensed games department not having enough money left after purchasing the Star Wars license. Decipher took the license instead.

But also: the Star Fleet Universe is an officially licensed setting, which due to a quirk in the 1979 license with Paramount, is a perpetual license which can't be revoked, but which can only use the TOS material, along with The Animated Series, but not named characters (so there are Vulcans but no Spock). And so its history and storyline has diverged from the mainstream Star Trek Universe. There have been five TTRPG iterations of the Star Fleet Universe (Prime Directive), though some appear to be vaporware:
PD1 (the original custom system)
