Warwick County Courthouses, also known as the Warwick County Courthouse and Clerk's Office, is a historic courthouse and clerk's office located at Newport News, Virginia. The original county courthouse was located closer to the James River at Warwick Town near Denbigh Plantation, but is no longer standing. The county moved it's seat to this location in 1810 and built a one-story, three-room, T-shaped plan Federal-style brick building. It has a slate-covered gable roof and exterior end chimneys. The building was later enlarged by a side and rear addition. The later courthouse was built in 1884, and is a two-story, Italianate style brick building. It has a rectangular plan and a shallow metal-covered hipped roof with three shallow cross gables. It features a square wood bell cupola that rises above the central projecting bay. Also on the property is a contributing Confederate monument dedicated in 1909. The buildings housed county offices until 1958, when Warwick County, Virginia combined with the City of Newport News.

It was listed on the National Register of Historic Places in 1988.
