The Government introduced the new minimum pay rate of £7.20 per hour for all staff aged 25 and over on 1 April.
It marked a 50p rise on the previous minimum hourly wage.
But the French hotel group – which employs over 5,000 people in the UK – is now paying all staff the higher rate.
Accor said investing in its employees was crucial to its ongoing growth.
Thomas Dubaere, managing director at AccorHotels UK & Ireland, said: “Sustainable performance and ambitious development plans are at the core of AccorHotels continuous growth strategy in the UK.
“We are proud to be part of an industry which is creating jobs and we want to take this opportunity to have all AccorHotels employees, including those under 25, on the NLW and above.”
Accor's portfolio includes the Sofitel, Mercure and ibis brands.
