Madeira Beach (/məˈdɛərə/ mə-DAIR-ə) is a city in Pinellas County, Florida, United States, bordered on the west by the Gulf of Mexico, and on the east by St. Petersburg.

[6] Prior to European colonization, the area that makes up what is now Madeira Beach was rarely permanently inhabited.

The modern shape of Madeira Beach was formed by a hurricane, the "Gale of '48", carving out the strait now known as John's Pass.

Significant dredging operations on the intracoastal causeway dramatically expanded the land area of Madeira Beach in the 1950s and 1960s.

[9] The city is located on a barrier island between the Gulf of Mexico to the southwest, and the Boca Ciega Bay to the northeast.

One bridge, the Tom Stuart Causeway, connects Madeira Beach to the mainland, in the unincorporated community of Bay Pines.

As of the 2020 United States census, there were 3,895 people, 2,001 households, and 1,310 families residing in the city.

It separated the barrier island on the coast and created a waterway known today as John's Pass.

John Levique, along with Joseph Silva, was the one who discovered it and named it after himself, and it is now a federally owned canal.

In 2022, the Governor of Florida, Ron DeSantis, included in the budget $1,500,000 to dredge John's Pass.
