The mother-daughter acting duo died within hours of each other last week and an official release from the Broadway League stated, "The marquees of Broadway theatres in New York will be dimmed in their memories ... for one minute."
The tribute will occur at 7:45 p.m. ET tonight.
Fisher, who died at age 60 last Tuesday, and Reynolds, who passed at 84 the very next day, both had rich careers in theater and on Broadway.
"Carrie Fisher wrote and most recently appeared on Broadway in the original solo show 'Wishful Drinking,'" the release said. "Her additional Broadway credits include 'Agnes of God' and 'Censored Scenes From King Kong.'"
Broadway League President Charlotte St. Martin said the mother and daughter had an "unmistakable bond" and shared an "ability to make audiences laugh, cry, sing and think."
The two are expected to be buried together on Friday at Forest Lawn Memorial Park in Los Angeles, according to Fisher's brother Todd.
