- This is the main article for Structures. For the category, see Category:Structures.

Structures are a group of buildings in My Singing Monsters. Each Structure has a unique function, most often helping you expand your Monster collection. For example, the Castle provides you with beds so that you can place more Monsters on your Islands, and the Breeding Structure allows you to Breed Monsters, while the Recording Studio allows you to record your own renditions of Monster sounds.
Certain Structures are available for purchase in the Market of most Islands, like the Hotel, Bakeries and Wishing Torches, while others are found on the Island when it is unlocked. Additionally, certain Structures can be upgraded using Currency.
My Singing Monsters is published in multiple languages. A table of translations can be found at Structure Translations.
