Yes (XenCenter), SCVMM (see details)
XenCenter is the central Windows-based multi-server management application (client) for XenServer hosts (including the open source version).
It is different to other management apps (e.g. SCVMM or vCenter) which typically have a management server/management client architecture where the management server holds centralized configuration information (typically in a 3rd party DB). Unlike these management consoles, XenCenter distributes management data across XenServer servers (hosts) in a resource pool to ensure there is no single point of management failure. If a management server (host) should fail, any other server in the pool can take over the management role. XenCenter is essentially only the client.
License administration is done using a separate web interface.

XenServer 6 introduced the ability to manage XenServer hosts and VMs with System Center Virtual Machine Manager (SCVMM) 2012. System Center Operations Manager (SCOM) 2012 will also be able to manage and monitor XenServer hosts and VMs. System Center integration is available with a special supplemental pack from Citrix.

Citrix announced with v 6.2 that several features will not be further developed and will be removed in a later release. These deprecated features function as in XenServer 6.1.0 and will remain supported, providing a period of overlap while third-party products or alternative solutions are established.

WLB has returned to XenServer 6.5 (Enterprise Edition) having been retired with the launch of XenServer 6.2. The deprecation notice for DVSC has also been rescinded within XenServer 6.5.

This initially included: Microsoft System Center Virtual Machine Manager (SCVMM) support
However, Citrix confirmed: Citrix is not deprecating support for SCVMM. However, SCVMM 2012 R2 does not currently support XS 6.2 (this being a Microsoft decision), because XS 6.2 was not released in time for this to happen).
