The piece that connects your saddle to the frame of the bike. The most important thing to know when shopping for a seatpost is the insertion diameter. This will be stamped at the base of an existing seatpost and will be measured in millimeters. The most common size is 27.2mm. It is very important that you replace a seatpost with one of an identical diameter.
