The 52-year-old actor, best known for appearing in Riverdale and Beverly Hills, 90210, suffered a stroke, according to reports in the US.
A spokesman for Perry told the Press Association he remains under observation in hospital.
Perry’s co-stars from past and present took to social media to wish him a speedy recovery.
Molly Ringwald plays Perry’s former partner on teen drama Riverdale and tweeted: “Sending my love to Luke Perry.”
Beverly Hills, 90210 star Ian Ziering shared a picture of himself and Perry embracing.
He said: “No words can express what my heart feels hearing today’s shocking news. Let us all say a prayer for his speedy recovery.”
Shannen Doherty, also a former star of Beverly Hills, 90210 appeared to send a message of support to Perry when she shared a picture of them together on the show.
