The Trafalgar St. James London, Curio Collection by Hilton is a contemporary boutique hotel located on the south side of Trafalgar Square in the City of Westminster, Central London, owned by London & Regional Properties.

Opened as The Trafalgar London in 2001,[2] the hotel was Hilton's first unbranded property.

The Trafalgar St. James is home to two restaurants including The Rooftop and Rockwell.
