Hanging with Hector is an Irish television series broadcast on RTÉ One. It is presented by the Irish personality Hector Ó hEochagáin. The show centres on Ó hEochagáin's exploits as he meets a different well-known individual for each episode and spends the day "hanging out" with them, engaging in their lifestyles and partaking in their chosen pursuits in a manner deemed entertaining for the Irish television viewing public. It has been criticised for being "about as original as washing your teeth each morning".

It is very similar to its more recent female equivalent Livin' with Lucy, although Ó hEochagáin, unlike Lucy Kennedy, does not actually live with the celebrities. The celebrities are largely male, with the most recent season including the chef Richard Corrigan, the former Irish rugby union international Trevor Brennan, the rugby analyst and radio presenter George Hook and, most recently, the horse trainer Aidan O'Brien. However, the female athlete Derval O'Rourke has featured in the past. The second season featured the comedian Jon Kenny and snooker player Ken Doherty. The first season included the fraudulent banker-turned CEO of Galway United F.C., Nick Leeson, the footballer Niall Quinn and Ó hEochagáin's schoolboy friend and future radio partner Tommy Tiernan.
