Croll Building, Renaissance Revival building in Alameda, United States.

The Croll Building is a three-story structure at the corner of Webster Street and Central Avenue. Its ground-floor restaurant keeps the stained glass, etched windows and carved wooden bar from the years when the neighbouring Neptune Beach amusement park operated (1917–1939). The upper floors hold a residential hotel and offices.

The first version of the Croll Building was erected in 1879 within Croll's Gardens amusement park. In 1908 it was moved to its present site at Webster Street and Central Avenue. As Croll's Gardens and Hotel it housed and trained boxers from 1883 to 1914, among them James J. Corbett, Bob Fitzsimmons, Jim Jeffries and Jack Johnson. It is a California Historical Landmark and is listed on the National Register of Historic Places.

In the early 1900s, renowned boxers like James J. Corbett and Jack Johnson trained within these walls, making it a hub for the sport. That legacy remains woven into the identity of the place today.

Today the building houses a restaurant on the ground floor, residential hotel rooms on the second level, and office spaces above. Visitors can easily access the exterior and public areas, though the interior is divided among different uses.

The building's first version was erected in 1879 in Croll's Gardens amusement park and moved to its present corner in 1908. The neon "Croll's" sign at Webster Street and Central Avenue now marks that relocated structure.
