I can tie the following with proficiency and they've served me well on my adventures:
Bowline
Figure 8
Clove hitch
Square knot
prusik
taut line
Mangus hitch
I know a few others but these are what I use 99% of the time (not including my shoes.)
I discovered recently that what I thought was the taut line hitch is actually the Mangus Hitch. Pretty close to the same thing except the finish. I've always just used a prusik knot on my tarp system but seems that many people on BPL prefer the taut line for some reason. I'll have to switch to it to see if I can perceive a difference in performance.
Edited to improve the general awesomeness of my response.
