The Alfa Romeo 1750 is a range of Compact executive car which was produced by Alfa Romeo from 1967 to 1977. The 1750 Berlina sedan was introduced in 1967, together with the 1750 GTV coupe and 1750 Spider. The 1750 models replaced the earlier Alfa Romeo Giulia Berlina. In contrast to the Giulia, the 1750s had reworked bodywork and bigger engine, shared many parts with other concurrent models in the Alfa Romeo range, but sold much less units during their production span.

The 1750 Berlina was based on the existing Giulia sedan, which continued in production. The 1750 was meant to top the sedan range, above the 1,300 cc and 1,600 cc versions of the Giulia. In the United States, however, the Giulia sedan ceased to be available and was entirely replaced by the 1750 Berlina.

The 1750 bodyshell had a longer wheelbase than the Giulia, and revised external panels, but it shared many of the same internal panels. The windscreen was also the same. The revisions were carried out by Bertone, and while it resembled the Giulia some of that vehicle's distinctive creases were smoothed out, and there were significant changes to the trim details.
