Florida's 23rd congressional district is an electoral district for the U.S. Congress, located in the Greater Miami area and covering parts of Broward County and southern Palm Beach County. In the 2020 redistricting cycle, it was drawn as a successor to the previous 22nd district and includes Boca Raton, Coral Springs, most of Deerfield Beach and Fort Lauderdale, and parts of Pompano Beach. The previous iteration of the 23rd district, which included Davie and Pembroke Pines, was instead renamed the 25th district. The district, along with two other districts in Greater Miami, has one of the highest concentrations of Jewish Americans, consisting of about 16% of the electorate.
