The most likely meaning is the NCAA Tournament Sweet 16. The latest search result I found for March 2026 shows the Sweet 16 bracket update in progress, with top seeds like Duke, Michigan, and Houston appearing in the round, but the available snippet does not provide the full finalized list yet.

If you meant March Madness

The clearest complete Sweet 16 list I found is from the 2025 men’s tournament, which included:

  • Alabama
  • Arizona
  • Arkansas
  • Auburn
  • BYU
  • Duke
  • Florida
  • Houston
  • Kentucky
  • Maryland
  • Michigan
  • Michigan State
  • Ole Miss

If you meant MTV

If you meant My Super Sweet 16 , that refers to the reality show about teens celebrating their 16th birthdays, and the notable cast members discussed in recent coverage include Natalie Viscuso, Sophie Mitchell, Alexa Victoria Jane, Darnell Robinson, and others.

Quick read

  • Sports: Sweet 16 = the NCAA Tournament’s regional semifinals.
  • TV: Sweet 16 = the MTV birthday show.

TL;DR: If you mean basketball, I can give you the Sweet 16 teams for the exact tournament year you want; if you mean the MTV show, I can list the cast or current updates.
