The humanity!
What are humanoids?
Humanoids in D&D are creatures of similar physical and intellectual capabilities as humans. This means they’re generally bipedal creatures, capable of intelligent speech and with a similar arrangement of limbs to a Human.
In the fantasy planes of D&D, this means there’s a huge variety in the types of creatures that fit within the humanoid umbrella. It covers smaller creatures like Dwarves, Halflings and Gnomes as well as larger creatures like Goliaths and Firbolgs. It includes aquatic races like Tritons and Merfolk as well as flying creatures like Aarakocra and Owlin. It even includes some creatures that might be considered monsters but many, like Orcs and Gnolls.
This does mean that there’s a huge amount of choice when using humanoids in your games, and this is fortunate as you’ll need a lot of them!
Humanoids are not only the most common creatures you’ll find in civilisation, they also tend to be quest givers, antagonists and victims. More so than any other creature type, humanoids have the propensity to be extremely weak or extremely powerful, and this is represented in the Monster Manual and Monsters of the Multiverse where there are many different varieties of humanoids for the different roles they fulfil, from bandits and assassins, to druids and archmagi.
Types of Humanoids
Below we’ve detailed all the different types of humanoids in D&D 5e. This can become a little complicated as sometimes, they are classified as different things depending on whether it’s a playable character or an NPC. In addition, sometimes their classification changes or isn’t in the most logical place. For example, Centaurs seem as humanoid as an Aarakocra for example, but the Monster Manual classifies them as monstrosities (hence their exclusion below). As a playable race though, Centaurs are considered humanoid.
The opposite is true for Thri-Kreen for example, who are considered humanoids in the Monster Manual, but their playable race profile lists them as monstrosities. In other instances, playable races are classified as humanoid, when they could just as easily be classified as another creature type. Eladrin are very much fey creatures while Firbolgs are giant-kin and Aasimar are part celestial.
To get around this, we’ve classified them as whatever they are classified as in Monster Manuals unless there’s no Monster entry, in which case, we’ve used their playable race profile.
Knowing what type of creature something is can be important though as some spells will only work on certain creature types (such as hold person/monster).

Using humanoids in DnD 5e
Humanoids work best in D&D when handling NPCs with complex motivations. If you simply need some great combat, monstrosities and many other creatures work well, but their motivations are often more straightforward and it’s difficult to negotiate with them. Humanoids have a complex range of motivations.
When using antagonists that are humanoids, give them back stories. Help the party to empathise with them and why they might be an antagonist. What’s even better with humanoids is that when you face a demon or a celestial or many other creatures, their persuasions are often relatively clear. Humanoids, however, fulfil the entire spectrum of alignments and motivations. This means knowing who is the enemy can be challenging. Imagine the party hunting down a cult, but not knowing who is a member of that cult, or a mysterious background figure pulling the strings of some great plot, only to discover it’s an important politician.
With these types of encounters, it’s easier to create meaningful social interactions with a party too. Talking your way into or out of a situation can be more tense than combat at times. Perhaps the party wants to infiltrate a cult or find which politician is corrupt.
