RO'CK of Ages: From Boom Days to Zoom Days is a 2021 book by Irish journalist and author Paul Howard, as part of the Ross O'Carroll-Kelly series.

[1][2] It is a compilation of newspaper columns previously published in The Irish Times between 2007 and 2021.

[3][4] The title is a reference to the hymn "Rock of Ages", the Irish economic boom, and the use of Zoom during the COVID-19 pandemic.
