The Titanic shipwreck lies at a depth of approximately 3.8 kilometers (about 12,500 feet or 2.4 miles) beneath the surface of the Atlantic Ocean. This extreme depth places it in the "midnight zone" of the ocean, where there is no natural light, the temperature is near freezing, and the pressure is immense, about 400 atmospheres or over 5,000 pounds per square inch.

This depth has made exploration both challenging and hazardous, requiring specially designed submersibles to withstand the intense pressure and darkness at that level.

Thus, the Titanic rests roughly 3.8 km deep on the ocean floor.
