Roderick Morris Buckenham de'Ath (/diˈɑːt/; 18 June 1950 – 1 August 2014) was a Welsh musician, best known for his role as drummer with Irish guitarist Rory Gallagher in the 1970s.

De'Ath was playing with the band Killing Floor when, at short notice, he was offered the job as a temporary substitute for Rory Gallagher's drummer Wilgar Campbell for a leg of a European tour in 1972.

"[1]: 121 After leaving Gallagher's band, de'Ath joined Ramrod (with Martin) and then he played with the Downliners Sect before moving to the United States.

Around this time, he suffered a serious accident while running to catch a train, which led to the loss of one eye and some brain damage.

[2] A few months later in August, de'Ath attended the funeral of former Rory Gallagher and Ramrod band member Lou Martin.
