Julius O'Riordan (born 26 October[1] 1966), better known by his stage name Judge Jules, is a British dance music DJ, record producer and entertainment lawyer.

[4] During his time at university, O'Riordan started hosting small parties where he was the DJ and earned the nickname "Judge Jules" due to his field of study.

As a young DJ he became known for his interpretation of beat at the Club Valentino venue in Colchester, Essex, drawing capacity attendance.

Through the radio show, he was responsible for launching many popular trance tunes and acts in the UK, and was a pioneer for commercial contemporary dance music.

He also has an internationally syndicated radio show called "The Global Warm Up" (also produced by Somethin' Else)[6] which can be heard across the US, Russia, Europe (including RTÉ 2fm) and the Middle East or via podcast.

[8] Alongside his full-time job as an entertainment lawyer, in 2019, O'Riordan still tours frequently as a DJ and continues to play at notable venues such as Zero Gravity Dubai and Ministry of Sound, and at events such as Luminosity Beach Festival, Creamfields and Dreamstate USA.

[12] In 2015, O'Riordan wrote a series of six articles for the 'Industry Insider' section of Mixmag which outlined basic legal advice for a number of music industry topics, including management, publishing and recording contracts.

In 2014, Eden nightclub was rebranded "Gatecrasher" and Judgement Fridays moved over the road to Es Paradis and combined with the Fiesta del Agua (water party).

Judgement returned to Ibiza in September 2018 for a one-off reunion show at Eden featuring Marco V alongside O'Riordan.

In 2019 O'Riordan returned once again to Judgement for a one-off workers' reunion in October also at Eden, alongside Dermot C, Dirty Rotten DJs and Tristan Ingram and Vicky Devine.

In 2012, O'Riordan signed with Paul Van Dyk's label VANDIT Records, releasing "The Attack" and "Give Me A Reason".

[14] In August 2017, O'Riordan released an original Loopmasters sample pack called "Judge Jules – Essential Big Room House".

O'Riordan appeared on the BBC's Top of the Pops show (2000) with Masterson, to perform the single "Pitchin'", from their album Hi-Gate.

In 2005 he was filmed while at the Global Gathering dance music festival where he was interviewed in a Bentley, and again by the same presenter in 2009 whilst being chauffeured in an Aston Martin to a gig in Bournemouth.

He also appeared on Channel Five's The Gadget Show, reviewing DJ equipment including a remote handheld DJing device known as a "pacemaker".

[21] He has lived in North London for the majority of his life, now settled in the Hampstead area with his wife Amanda, their son Jake and daughter Phoebe.
