Two-time Wimbledon champion Andy Murray will play at the Libema Open in 's-Hertogenbosch, the Netherlands, this June.
It is the first confirmed event the 30-year-old will play after undergoing hip surgery in January.
Murray has not played in the Netherlands since reaching the quarter-finals of the Rotterdam Open in 2015.
"It's the perfect way for me to prepare for Wimbledon," said the former world number one.
"I've heard lots of good things about the tournament and the courts are meant to be very good."
The grass-court tournament - formerly known as the Ricoh Open - will take place from 11-17 June.
