Both players missed penalties in Sunday's Euro 2012 quarter-final shoot-out defeat by Italy in Kiev.
And yesterday it emerged attacks had been launched on the popular social networking site.
"We are concerned at the reports regarding allegations of abuse aimed at England players Ashley Cole and Ashley Young on Twitter," an FA statement read.
"They have just given everything for the national team at Euro 2012 and it is appalling and unacceptable that messages of an abusive type are being posted. We support any police investigation in identifying who is behind this."
Cole and Young, who returned home with the remainder of the team yesterday, were singled out for abuse on Twitter by one user following the 4-2 shoot-out defeat.
