The First Four of the 2025 NCAA tournament starts Tuesday with a pair of games on the men's side in Dayton, Ohio, as March Madness officially gets underway. Start times for each of the first-round games are set, along with all the TV broadcast info.

Madness is upon us — after the First Four games Tuesday night, the first-round games of the NCAA men's basketball tournament are Thursday and Friday. That includes four first-round games Friday at Fiserv Forum in Milwaukee.

The First Four has been around since 2011 and features the last four automatic qualifiers and last four at-large bids playing to whittle the field from 68 to 64. This year will see two 16-seed vs. 16-seed matchups and two 11-seed vs. 11-seed matchups, but don’t write these games off because they involve double-digit seeds.
