Broadway is a street in the City of Westminster in London that runs between Petty France, Queen Anne's Gate, Carteret Street and Tothill Street in the north and Victoria Street in the south. It is joined on the west side by St Ermin's Hill and Caxton Street, and on the east side by Dacre Street.

Notable buildings on the street include:

• St Ermin's Hotel, on the corner with Caxton Street which had strong connections with the British intelligence community. Grade II listed.

In March 1973, the Provisional IRA placed a car bomb outside the post office at No. 1, Broadway. It was defused before it exploded, but two other devices, one in Whitehall and another near the Old Bailey, exploded that day, killing one person who died from a heart attack attributed to the bombing, and injuring over 200.
