Narrative:

We were flying on the last leg of a 4 day trip. Preflight; takeoff; and climb to our cruise altitude of FL370 were all normal. We had been at cruise about 1 hour. Captain was PF. We were just past ZZZ when we got an EICAS low oil pressure message; the engine oil pressure light and the oil quantity was showing 0. We declared an emergency and the captain said to run the appropriate checklists. We ran the low oil pressure; engine failure/shutdown and drift down checklists. The center immediately suggested that ZZZ was the nearest airport; and we agreed. The captain coordination with the purser and told her the aircraft status and that we would be turning around and landing in approximately 20 mins under a cabin advisory. He made more than 1 PA advising the passenger what was happening. We requested a vector to ZZZ and a 10 mi final to runway 8. We also requested landing data for ZZZ with our estimated landing weight; since we were close to maximum. The captain made a fantastic approach and landing; approximately 30 mins from engine shutdown. We asked tower; rescue and the flight attendants to look for any damage to the left engine that would prompt an evacuate/evacuation. All responses were negative. Customer service did a fantastic job in a bad situation dealing with the passenger. I can't say enough about the captain and his professionalism. His calm manner throughout this had a great effect on the entire aircraft. He took command of the situation; while at the same time constantly seeking my input and confirming any actions he was going to make. I felt totally in the loop with him and part of the team. Once on the ground; he spent a great deal of time with the passenger answering their questions and making them feel at ease about getting on the replacement aircraft. He turned a bad situation into a plus in that many passenger told us how impressed they were with how he and the company handled this. Callback conversation with reporter revealed the following information: the reporter stated that the low oil pressure EICAS message appeared; and the flight crew observed the oil quantity decreasing. The left engine was shut down to prevent an engine seizure; and the landing was 2000 pounds below maximum landing weight.
