Major League Baseball stadiums: current, future, and notable former parks

Common characteristics

• Capacity and seating: Most stadiums hold tens of thousands of spectators, often with a mix of general seating, luxury suites and club areas.
• Field surface: Natural grass remains common, though several parks use artificial turf or hybrid systems.
• Roof and weather control: Some venues have open-air designs, while others feature retractable roofs or full domes to deal with climate extremes.
• Unique features: Outfield wall angles, manual scoreboards, and historic landmarks can create distinctive playing conditions.

Historically, ballparks evolved from simple wooden stands to ornate concrete-and-steel parks in the early 20th century and to multiuse domes and modern single-purpose facilities later on. Two of the best-known surviving parks are Fenway Park and Wrigley Field, both early-20th-century venues that remain iconic for their original design elements. Newer stadiums incorporate large video boards, expanded concessions, and premium seating to meet modern expectations.

Beyond regular-season games, stadiums host postseason play, concerts, charity events, and occasionally other sports. Naming rights and corporate sponsorships have become a major revenue source; many parks carry corporate names that change over time.

Lists of current, planned, and notable former MLB parks are maintained by several reference sources; for a curated compilation see a Comprehensive list of MLB stadiums and for historical notes consult park histories and timelines. Distinguishing features—such as a park's age, roof type, or playing surface—are often highlighted to compare venues and their impact on the game.
