Spanish Affair is a 1957 American–Spanish co-produced drama film directed by Don Siegel and Luis Marquina.

The film's sets were designed by the art directors Tambi Larsen and Hal Pereira.

Merritt Blake, a young American architect, comes to Spain to close a series of commercial agreements.

When he learns that he will need to convince three Spanish architects of the design which he has proposed, he insists on inviting Mari (Antonio's assistant) to function as interpreter.

They set off, first to visit the Conde de Rivera, who tells Merritt that he will support the project if his colleague in Barcelona favors the plan.
