The 1990 Chilean telethon was the ninth version of the solidarity campaign conducted in Chile, which took place on 7 and 8 December 1990. The theme of this version was "No-one Left Out."
The poster girl was Daniela Muñoz. The telethon was held after 24 months as in 1989 the event was suspended by presidential and parliamentary elections.
This was the first telethon to be held in Chile after the return to democracy and under the leadership of President Patricio Aylwin.
The final figure came to CL$1,153,291,010.

Juan Ramón Mocedades Luz CasalAt 7:45 on Saturday, December 8, 1990, coinciding with the Feast of the Immaculate Conception, Channel 13 and TVN left the live transmission to deliver the mass. For this reason, the News Section was broadcast only by UCV TV, Channel 8 (La Serena), Channel 10 (Valdivia), Telenorte, Megavisión, Channel 11 and Red TV Cable.
On the final block of the event, Univision broadcast the transmission from the theater to the affiliated channels (except for Televisa's channel s), which helped in putting thoughts for a Teletón to be held in the US and Mexico.
The supposed goal was 711,712,019 pesos, but the organization wanted to reach a milestone goal of 1,000,000,000 pesos, which was met at the final tote of 1,106,098,601 pesos causing the tally board to put 1 in the Cash ($) sign as it was only capable of 9 numbers instead of 10.
