Ms Long said the flag bearing the logo of the KKK appeared off Island Street on Monday.
She has slammed those responsible, commenting that the flag has added "an even more sinister edge" to recent race-related incidents in the city.
Ms Long said she had received a number of complaints from constituents and has informed the PSNI.
A police spokesperson said they held discussions with local representatives, who then removed the flag on Tuesday.
It is absolutely outrageous, how some local idiot puts up a flag and gets a reputation for the area... This does not represent the people of east Belfast; it doesn't represent the unionist or loyalist community.
First Minister Peter Robinson
Ms Long commented: "Yet again we see those who wish to bully anyone different from them use flags and emblems to assert dominance and control over a community. To do so at all is to be condemned but to put up these flags in broad daylight shows just how brazen the culprits are.
"To use flags hailing a hate group such as the KKK is sickening and lends a further menacing element to recent events. It is essential that every right-thinking person unites against those who engage in racist, bigoted or otherwise intolerant behaviour and does so with consistency.
"It is also critical that the all-party talks this week stop ducking the issue of the use and abuse of flags and emblems for the purposes of intimidation, and face up to dealing substantively with this challenge to a shared future and to the rule of law."
East Belfast DUP MLA Robin Newton has also condemned those who put up the flag.
"Across Northern Ireland there are many streets decorated for the celebratory period around the 12th July. The erection of a Ku Klux Klan flag in East Belfast has no place as part of these celebrations, or anywhere in our society," he said.
"The flying of such a flag is disgusting. It does not represent the people of East Belfast, of loyalists, and particularly of all those people who today, remember the sacrifice of those men who laid down their lives at the Battle of the Somme."
Michael Copeland, Ulster Unionist MLA for the area, added: "I welcome the fact that the flag has been swiftly taken down, but it should never have been put up in the first place.
"A defunct American racist organisation has absolutely no connection or affinity with the people of East Belfast," he said.
"Whoever put the flag up clearly has little or no understanding of his or her culture or history. This on a day when we pause to remember the sacrifice of the Ulstermen and Irishmen who died for our freedom, in the uniform of the British Army on the first day of the Battle of the Somme on 1 July 1916."
