Use the cancel() or registerCancellation() method of the \Magento\Sales\Model\Order class.
The cancel() method calls the registerCancellation() method internally, and additionally makes a payment transaction for the cancellation.

How is \Magento\Sales\Model\Order::cancel() implemented and used?

How is a payment method's cancel() used?

How is the \Magento\Sales\Model\Order::STATE_PENDING_PAYMENT constant used?

How does the Authorize.Net module restore a quote from an order in the case of a payment failure?
