Who Was Niamh O’Brien, Michael Flatley’s Wife?
Niamh O’Brien was a talented Irish dancer from County Meath. She started dancing young, competed at a high level (including placing in the World Irish Dancing Championships), and later performed professionally. She danced the lead role of Saoirse in Lord of the Dance and appeared in other Flatley productions such as Feet of Flames and Celtic Tiger.
She was known for her grace, strength, and quiet support behind the scenes. Friends and colleagues often described her as warm and devoted both as a performer and as a wife and mother.
How Michael Flatley and Niamh O’Brien Met and Married
The pair first crossed paths through dance. Niamh performed in Flatley’s shows for years before their romance began. Sources close to them spoke of an “immediate attraction.”
They started dating in June 2006 and moved quickly. Just four months later, on October 14, 2006, they married at St. Patrick’s Church in Fermoy, County Cork. Niamh wore a custom Badgley Mischka gown, arrived in Flatley’s Rolls-Royce Phantom, and the reception took place at his Castlehyde House estate. About 250 guests attended the celebration.
Flatley was 47 or 48 at the time; Niamh was 32. Before the wedding he told the Sunday Times, “She’s the most beautiful girl in the world, inside and out. She is exactly what I was hoping my wife would be.”
Family Life: Their Son and Shared Years
A year after the wedding, in 2007, the couple welcomed their only child, son Michael St. James Flatley. Flatley has spoken proudly of him as an academic, creative young man who plays the flute and electric guitar and has interests in acting and directing.
The family largely kept a private life while Flatley continued his career and later faced his own health challenges, including cancer treatment in 2023 (now in remission). Niamh stood by him throughout. In early 2026 Flatley even teased special plans to renew their vows for their 20th anniversary, saying he felt like “the luckiest guy in the world.”
