San Marino participated in the Eurovision Song Contest 2021 in Rotterdam, the Netherlands. The Sammarinese broadcaster San Marino RTV (SMRTV) internally selected Senhit as their representative with the song "Adrenalina" featuring Flo Rida. Senhit was due to compete in the 2020 contest with "Freaky!" before the event's eventual cancellation and had also served as the nation's 2011 entrant. "Adrenalina" was written and composed by Thomas Stengaard, Joy Deb, Linnea Deb, Jimmy Thörnfeldt, Kenny Silverdique, Suzi Pancenkov, Malou Linn Eloise Ruotsalainen and Chanel Tukia, along with Senhit and Flo Rida themselves. While Flo Rida had provided vocals for the track, his participation in the performance of the song on the Eurovision stage was only confirmed on the day of the second semi-final due to COVID-19-related travel restrictions.
To promote the entry, a music video for the song was released and Senhit made appearances on Polish and Albanian television as well as at a Eurovision Party in Spain in the lead up to the contest. San Marino performed first in the second semi-final of the Eurovision Song Contest 2021, held on 20 May 2021, and placed 9th, receiving 118 points. The entry qualified for the final held two days later, where the nation placed 22nd with 50 points. This marked their second-best placing to this point and their third qualification for the final.
