Since everyone that has answered is completely wrong i will answer. Below I've included the link the the GRACE satellite gravity maps. GRACE has been in orbit for years plotting the strength of gravity on the planet, with surprising results. One of the lowest points of gravity is in the Indian Ocean. There are fluctuations, of course, for a variety of factors; the density changes in the liquid mantle of the earth, even seasonal rainfall in south America affects the strength of gravity in the region. the list goes on and on. I recommend looking around the GRACE site, it has very good information and gravity maps!
I retract that, the below poster is right. :) Although i stand by my statement with one change, that without the polar anomalies the lowest point is in the Indian Ocean...

Try the Oregon Vortex. Anywhere you can stand sideways has to have the lowest gravitational field.

The GRACE gravity data and maps are relative to the geoid -- that is, they are the gravity anomaly left after subtracting the major effect of latitude. The range is about -70 mGal to +70 mGal, or +/- 7 parts per million.
The net gravity at the poles, on the other hand, is about 0.5% less than on the equator, which is 10,000 times more than the gravity anomalies.
Mt. Everest is 8,848 meters high, and gravity on a mountain decreases about 0.2 mGal for every meter -- so at the top, it is about 0.17% less than it would be at sea level.
The South Pole is at a elevation of about 2,900 meters; so besides the general 0.5% decrease for being at the pole, it also has about 0.06% less for being up high.
South Pole is my vote for the world's lowest gravity (on the surface). Haven't figured out the gravity down at the bottom of a deep mine.

Gravity s the least at the equator by 1 dram per every 190 drams when comparedwith an individuals weight at the poles. Included is the web site for further research.

On top of Mt. Everest because gravity follows the inverse square law. The top of Everest is the farthest you can get from the center of the earth and still be on the planet.

North pole? I have NOO idea thats a good question
