when does baseball start

For 2026 in the U.S., “baseball starts” at a few different times depending on what you mean :

• The 2026 college baseball season (NCAA Division I) starts on Friday, February 13, 2026.

• The 2026 Major League Baseball (MLB) regular season starts with an Opening Night game March 25, 2026 (Giants vs. Yankees), then a full Opening Day on March 26, 2026 for the other 28 teams.

• In general, MLB seasons start in late March or early April and run about six months through late October or early November.

So if you’re thinking “big pro baseball on TV,” circle March 25–26, 2026. If you’re into college ball, it actually starts a month earlier, on February 13, 2026.
