The country music icon, 76, joined the social media platform on Sunday.
In her first-ever post, Parton shared a video composed of various clips of her from throughout the years, backed by the intro of her megahit song, "9 to 5."
"I have arrived!" the singer-songwriter captioned the post, adding two hashtags: "#HeyItsDolly" and "#DollyTok."
On Twitter, Parton celebrated her new social media presence by tweeting a link to her TikTok account. "Better late than never," she wrote in her caption.

Parton has since uploaded a series of other videos on TikTok after her inaugural post, including one where she acknowledged that she missed out on seeing fans' Parton-related content. "Now that I'm here, tag me!" she wrote alongside a red heart emoji.
One other post shows Parton playfully tossing a cookie as her new song, "Berry Pie" plays in the background. "I like to cook, and I love to bake / Bread and cookies, and pies and cake," she sings on the tune.
The song, released with SoundOn — TikTok's music marketing and distribution platform — is available exclusively on the social platform. It's "a sugary, down-home ditty that draws from traditional bluegrass styles," per a press release from TikTok.

"'Berry Pie' is the ideal soundtrack for holiday baking adventures–successes or blunders! Whether you're a professional patissier or attempting your first tart," the company added.
In another TikTok post, Parton uses her southern-style coconut cake mix to craft a tasty treat. "I've had my fair share of baking blunders, and the holidays are full of them! Share your holiday #bakingblunders with me using #berrypie🧁," she captioned the clip.
