How many cities have a monument called "Cleopatra's Needle"?

London, Paris, and New York City all have an obelisk monument with the popular name of "Cleopatra's Needle".

These three monuments are ancient Egyptian obelisks that were re-erected in the 19th century. The ones in London and New York are a pair. The one in Paris has a twin in Luxor, where it is originally from.

All three are genuine ancient Egyptian, but actually have nothing to do with the famous Egyptian queen. They were already over a thousand years old at her time. The London and New York pair were made during the reign of the 18th Dynasty Pharaoh Phutmose III. The Paris needle dates from the reign of the 19th Dynasty Pharaoh Ramses II.

The Paris needle was the first to be moved and re-erected. The New York one was the first to get the French nickname "L'aiguille de Cléopâtre" (Cleopatra's Needle). It received this nickname while it still stood in Alexandria.

The London needle is in Westminster, on the Victoria Embankment. The New York needle is just west of the Metropolitan Museum of Art. The Paris needle is in the Place de la Concorde.

Since there is a 4th obelisk in Luxor, you might ask why the answer is not 4. The reason for this is the fact that the Luxor obelisk has never been called Cleopatra's Needle. You might then ask then why does the one in Paris count? This is because it has sometimes mistakenly been called this. It is more often called the Luxor Obelisk.
