Here is an exhaustive list of Universal Monster Movies including the new Universal Monster Universe. I will be adding more of those as they are released. If you feel that there is something missing, feel free to suggest an addition. I realize Dracula '92, Frankenstein '94 and Gods and Monsters '98 are not Universal properties but I feel they are closely related and relevant.
Last updated June 29th: Added Dracula, Frankenstein, The Mummy, Invisible Man, Wolf Man and Dr. Phibes franchises (Monsters, Hammer and Modern), Witchboard 1-3 and 28 Months Later. Films yet to be added (missing in database): Halloween Kills, Halloween Ends, Amityville 1974, Beyond the Green Inferno, The House on the Edge of the Park 2, Pumpkinhead (remake), Cannibals (sequel to Cannibal Holocaust), Laid to Rest: Exumed, Shrooms 2, Hellraiser (reboot) and TV series.
The Universal monsters are fictional monsters that figured in various horror, suspense and science fiction films made by Universal Studios during the decades of the 1920s through the 1950s. Universal introduce franchises like Dracula, Frankenstein, The Mummy, The Invisible Man, The Wolf Man and Creature from the Black Lagoon.
Universal Horror or Universal Monsters - phrases used to describe the horror, suspense and science fiction films made by Universal Studios during the 1920s - 1950s.
Horror/Monster franchises include: Phantom of the Opera, Dracula, Frankenstein, Edgar Allan Poe, Mummy, Invisible Man, Werewolf / Wolf Man, Paula, the Ape Woman / Gorilla Girl, Inner Sanctum Mysteries, Creeper, Abbott & Costello, Gill Man / Creature from the Black Lagoon.
Universal has plans for rebooting the franchise. Starting with The Mummy (2019) as an origin story. [Though Dracula Untold (2016) was first and also an origin story, it is downplayed as the restart and said not part of Dark Universe canon). The new reboot Monster franchises include Creature from the Black Lagoon, Dracula, Frankenstein, Hunchback of Notre Dame, Invisible Man, and Phantom of the Opera. As of late 2017, those plans seem to have stalled.

The rest of the list is not in order and not a definite list.
