Ashley Young and Ashley Cole were targeted after missing penalties in England’s Euro 2012 quarter-final loss to Italy on Sunday.
A Metropolitan Police spokesman said: “We are aware of alleged racist comments on Twitter following last night’s England game and have launched an investigation.
“The allegation was made to MPS on 25 June by a member of the public relating to comments on a Twitter account supposedly based in London.
“No arrests at this early stage.
The Football Association branded the Twitter attacks as “appalling and unacceptable”.
“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.
