Naples is a neighborhood of Long Beach, California, United States, built on three islands located in Alamitos Bay. The islands are divided by canals which open into the bay. Most of the streets on the island have Italianate names. The center of Naples features a large fountain which serves as a popular meeting spot. The city was named after the Italian city Naples.

Naples was once marshland within the artificial Alamitos Bay, at the mouth of the San Gabriel River. Around 1903, Arthur M. Parsons raised $500,000 from investors and purchased the marshland from the Alamitos Land Company. Construction began in August, 1905, reshaping the existing land and water into the three islands of Naples. The design was by the firm Mayberry & Parker, who also contributed to the Hotel Wentworth in Pasadena. The concept of canals and gondolas was similar to the "Venice of America" developed by Abbot Kinney up the coast. Parson's Naples Land Company called its plans the "Dreamland of Southern California," and projected that "through the canals and under the high arching bridges gay gondoliers will propel their crafts like those in the waters of the Adriatic under the blue skies of Italy." The project was completed in the 1920s, then rebuilt after the 1933 Long Beach earthquake.

From 1904 to 1950, the neighborhood was served by the Pacific Electric Balboa Line.
