# Duplicate themes with the Admin GraphQL API

Starting in version 2025-10, the GraphQL Admin API includes a `themeDuplicate` mutation to duplicate store themes. The mutation accepts a theme ID and an optional `name` parameter to rename the duplicated theme.

For further details, refer to the [`themeDuplicate`](https://shopify.dev/docs/api/admin-graphql/2025-10/mutations/themeDuplicate) reference documentation.
