Wednesday's meeting at Leopardstown has been called off following an 8.30am inspection.
Officials were forced to check conditions after overnight rain was heavier than expected.
The track tweeted: “Following greater overnight rainfall than anticipated and with further rain this morning, parts of the track have been left unfit for racing with no improvement expected.”
They added in a press release that the decision came; “following eight millimetres of rain overnight and further rain forecast.”
