3-D Docking Mission is a game for the Apple II family of computers created in 1978 by programmer Christian Oberth. The game was published by Programma International and by The Elektrik Keyboard of Chicago, Illinois.

The object of 3-D Docking Mission is to maneuver a spacecraft through an asteroid field and safely dock with its mothership. The ship begins each round with a limited supply of fuel (40 points) which is consumed as the player uses thrusters to pilot the craft. The game ends as a loss if the player's ship runs out of fuel, collides with an asteroid or runs too quickly into the mothership. If the ship reaches the mothership and successfully enters the docking port, the player wins the round and a new one begins with more densely grouped asteroids.

The game presents the player with two views of the playing area — one from above and one from the side. Using these views, the player selects among six thrusters to fire, controlled by keys on the keyboard: T and B to move up and down, < and > to move left and right, and H and F to move forward or backward.

At the bottom of the screen is a display showing the amount of time the player has taken and the amount of fuel remaining, as well as the current score and the high score.
