I can help with that. Here’s a concise answer based on available context and common knowledge up to 2025. Direct answer:

• Mirabel Madrigal from Encanto is 15 years old. This places her as the youngest sibling in the family group whose ages are discussed in various fan sources and official materials, though the exact ages of other siblings vary slightly depending on source.

If you’d like, I can pull the latest official statements or fan-davorite sources to reconcile any discrepancies about each family member’s age.
