ImagoRicciardo won both Monaco races in 2010.
The Australian, who won and finished second last time out at Spa, will line up on the front row alongside the New Zealander Brendon Hartley (Gravity-Charouz).
"The laps I did in the Toro Rosso during F1 free practice didn't put me off at all," he said. "In fact, quite the opposite.
"We saw a major improvement in performance between the first and second set of tyres, the track conditions were getting better all the time and I really thought that group B was going to be quicker than us.
"Last year, I won here after starting from pole, so I hope to do the same again this year."
On the second row is Robert Wickens (Carlin) and Alexander Rossi (Fortec Motorsports).
With concerns over traffic on the twisty street circuit, the drivers were split into two groups.
Ricciardo and Wickens were in Group A, with Hartley and Rossi in Group B.
