+```ts
+function createQueriesController<TQueryOptions, TCombinedResult>(
+   host,
+   options,
+queryClient?): QueriesResultAccessor<TCombinedResult>;
+```
+
+Defined in: [packages/lit-query/src/createQueriesController.ts:701](https://github.com/TanStack/query/blob/main/packages/lit-query/src/createQueriesController.ts#L701)
+
+Creates a Lit reactive controller that subscribes the host to multiple
+queries.
+
+The returned accessor is callable and also exposes `current` and `destroy`.
+When `options` or `options.queries` is a function, it is re-read during host
+updates so the query list can follow reactive host state.
+
+If `queryClient` is omitted, the controller resolves the client from the
+nearest connected `QueryClientProvider`.
+
+## Type Parameters
+
+### TQueryOptions
+
+`TQueryOptions` *extends* `any`[]
+
+### TCombinedResult
+
+`TCombinedResult` = `CreateQueriesResults`\<`TQueryOptions`\>
+
+## Parameters
+
+### host
+
+`ReactiveControllerHost`
+
+The Lit reactive controller host that owns the queries
+subscription.
+
+### options
+
+[`Accessor`](../type-aliases/Accessor.md)\<[`CreateQueriesControllerOptions`](../type-aliases/CreateQueriesControllerOptions.md)\<`TQueryOptions`, `TCombinedResult`\>\>
+
+Queries controller options, or a getter that returns options.
+
+### queryClient?
+
+[`QueryClient`](../classes/QueryClient.md)
+
+Optional explicit query client. Provide this for
+controllers that should not resolve a client from Lit context.
+
+## Returns
+
+[`QueriesResultAccessor`](../type-aliases/QueriesResultAccessor.md)\<`TCombinedResult`\>
+
+An accessor for the latest query results, or the value returned by
+`combine`.
+
+## Example
+
+```ts
+import { LitElement, html } from 'lit'
+import { createQueriesController } from '@tanstack/lit-query'
+
+class DashboardView extends LitElement {
+  private readonly dashboard = createQueriesController(this, {
+    queries: [
+      { queryKey: ['stats'], queryFn: fetchStats },
+      { queryKey: ['projects'], queryFn: fetchProjects },
+    ],
+    combine: ([stats, projects]) => ({
+      stats: stats.data,
+      projects: projects.data ?? [],
+      isPending: stats.isPending || projects.isPending,
+    }),
+  })
+
+  render() {
+    const dashboard = this.dashboard()
+    return html`<p>Projects: ${dashboard.projects.length}</p>`
+  }
+}
+```
