Championship leader Lewis Hamilton claimed his first pole position around the streets of the principality, beating his Mercedes team-mate to the top spot.
The Silver Arrows continue to have the pace advantage over their competitors and thus engaged in an exclusive battle for P1.
Hamilton trailed Nico Rosberg by nearly four tenths of a second after Q2, but reversed the positions by just over a tenth of a second after their first runs in the all-important top ten shootout.
The defending champion found even more lap time on his final run in Q3, while Rosberg abandoned his after locking up heavily at Sainte Devote.
That left Hamilton 0.342 seconds clear earning his 43th pole position in the sport and his first at Monaco.
Ferrari’s Sebastian Vettel was the only other driver to lap below one minute, 16 seconds as he secured third place, just under two tenths of a second ahead of Red Bull Racing’s Daniel Ricciardo, who also failed to improve on his second run in Q3.
Team-mate Daniil Kvyat did find time on his second run to take fifth, ahead of the Ferrari of Kimi Raikkonen.
Force India’s Sergio Perez hustled the VJM08 to a superb seventh place, just ahead of Carlos Sainz, Pastor Maldonado and Max Verstappen, who all ended up on the same tenth in eighth, ninth and tenth.
Romain Grosjean failed to join his Lotus team-mate Maldonado in Q3, after locking up at the second part of the Swimming Pool on his quickest lap in Q2.
An expected five-place grid penalty for a gearbox change ahead of the event means Grosjean will start P16 in Sunday’s Monaco Grand Prix.
McLaren-Honda was confident of getting both cars through to Q3 for the first time this season, but neither made the cut.
Fernando Alonso’s car suffered a suspected electrical problem before he could complete a flying lap in Q2, while team-mate Jenson Button was less than a tenth of a second away from making the top ten.
The 2009 race winner described the situation as “painful” when he learned of his fate, having had to slow for yellow flags – after Rosberg locked up and went off at Ste Devote – on his final flying lap.
Force India’s Nico Hulkenberg was lucky to get away with striking the wall at Mirabeau in Q1 and ended up P13, just under 0.2 seconds adrift of team-mate Perez.
Williams struggled badly in Monaco, with Felipe Massa winding up P14 while team-mate Valtteri Bottas ended up being the highest-profile casualty in Q1.
Bottas was more than six tenths of a second away from making the cut and wound up P17, between the Saubers of Felipe Nasr and Marcus Ericsson.
The Manor/Marussias were over two seconds further back in filling the final row of the grid.
Will Stevens was three tenths quicker than team-mate Roberto Merhi through the first sector of their quickest laps, which proved crucial in the final reckoning.
So an important qualifying for Lewis Hamilton. Track position at Monaco is vital as overtaking is limited around the tight and twisty street circuit.
Nico Rosberg will need to be in a racy mood or have a great strategy to score that hat-trick of wins. Sunday’s Monaco Grand Prix is going to be fascinating. Bring on the street fight.
