Dini Petty (born January 15, 1945) is a Canadian television and radio host. At 22, wearing a trademark pink jumpsuit and working for Toronto radio station CKEY, she became the first female traffic reporter to pilot her own helicopter. She clocked 5,000 hours as pilot-in-command of a Hughes 300.

Later, at Citytv Toronto, she worked as a writer, reporter and co-anchor, with Gord Martineau, of evening newscast CityPulse at 6.^[1] There she also hosted an afternoon program, Sweet City Woman. Later, on Citytv's daily talk show CityLine, Petty established herself as one of Canada's foremost television talk show hosts.^[2][3] She left her evening news anchor position to concentrate on CityLine. From May 1987 to 1989, Petty also anchored Citytv's short-lived 5:30 p.m. news and current affairs program CityWide.

In 1989, Petty moved to CFTO and the Baton Broadcasting System.^[4] Her popular hour-long general interest talk show, The Dini Petty Show, aired until 1999.^[2][3]

In the 2000s, Petty hosted Weekends with Dini Petty, a syndicated weekly radio program focused on health and wellness for baby boomers. Sheila Copps succeeded her as host of Weekends.

In August and September 2010, Petty returned to guest-host several episodes of Cityline while host, Tracy Moore, was on maternity leave.

In 2016, Petty relaunched a product called Luuup Litter Box, partially through using a Kickstarter platform.^[5]

Petty is the daughter of Gordon Petty, a film producer, and Molly, a Scottish war bride.^[2] Molly Petty ran a talent and modeling agency, Producers' Services in Toronto.^[2] In 1980, a documentary camera followed her pregnancy and the birth of her son Nicholas.^[6] She also has a daughter, Samantha.

Petty has written a children's book, The Queen, the Bear, and the Bumblebee, published in 2000.^[7] Joanne Findon (professor of English literature at Trent University, Ontario)^[8] described the book as "a charming fable about the value of being yourself and recognizing your own strengths."^[9] Publishers Weekly was less flattering: "Despite a bumblebee protagonist, there's little to buzz about in this didactic picture book."^[10] In 2014, the book was staged at a theatre at the Banff Centre.^[11]
