Seth Rogen and Joe Rogan are not related. There is some confusion regarding the two after Seth tweeted in 2013: “Hey @joerogan. Do people always spell your name RogEn? Or am I the only one getting f***ed here?” Joe Rogan didn’t reply.
Seth Rogen is a Canadian actor and comedian who was born on April 15, 1982, in Vancouver, British Columbia, Canada. He comes from a Jewish family.
“My family has looked into our ancestry, and it’s pretty straightforward,” he told Den of Geek in 2020. “I mean, my grandmother was an immigrant – came to Canada from Poland. So my roots back to the old-folk country are not that far. I am an Ashkenazi Jewish person.”
Rogen said he got his American citizenship when he was 10.
On the other hand, Joe Rogan is an American podcaster who was born on August 11, 1967, in Newark, New Jersey.

“My grandfather on my father’s side, Pappy Rogan is straight off the boat from Ireland,” he posted on X. “I’m 3/4 Italian 1/4 Irish.”
In 1985, he graduated from Newton South High School.

“I just wanted to know what was going on, but it was all things I knew,” Rogan revealed in episode #2227 of his podcast in 2023. “Mostly Italian, some Irish, 1% Asian, 1.6% African. I think the Asian is probably Genghis Khan sh*t.”
