Lorelei Shannon (born 1965 in Mesa, Arizona) is an American writer of horror and computer games.
She co-edited the anthology Hours of Darkness for Scorpius Digital Publishing, which contained stories by well-known horror authors such as Ramsey Campbell, Peter Crowther, Dennis Etchison, Joe R. Lansdale, and Richard Christian Matheson.
Shannon co-designed King's Quest VII, a 1994 installment in Sierra Entertainment's King's Quest computer game series, with Sierra founder Roberta Williams.
Shannon's sequel to Roberta Williams's horror game Phantasmagoria, called Phantasmagoria: A Puzzle of Flesh, caused a storm of controversy when it was banned in Singapore and Australia for violent and sexual content.
Throughout Shannon's time at Sierra On-Line, she wrote material for many classic Sierra games such as Laura Bow and Police Quest, and worked with many of Sierra's "stars", such as Scott Murphy, Al Lowe, Corey Cole, Josh Mandel, and Jane Jensen.
