You're probably looking for the Toastmasters Icebreaker speech.

"Icebreaker" is the name of the first speech in the Toastmasters Pathways program: a 4-to-6-minute talk that introduces yourself to your club. The official guidance lives on the Toastmasters Pathways site — start there.

If you came here for the other meaning, this site runs free, real-time multiplayer icebreaker games for team meetings (retros, all-hands, standups, onboarding). The home page is the right place.
