There are several dozen known periodic comets, and we have observed many long-period comets as well. New ones are discovered every year. In fact, a new comet was discovered last fall, and should be nicely visible in the spring.
If you are referring to Halley's Comet, it was last seen in 1910 and then in 1986, and is expected to be back around in 2061 or so. However, observations of Halley's Comet go back to the 3rd century BC. Check the Related Links below for more info.
No, Halley's Comet was last visible from Earth in 1986 and is expected to return in 2061. It has an orbital period of about 76 years.
Approximately every 76 years 1986 + 76 = 2062
Hopefully some serious advances in medicine come about, as we will need them to view this comet again. It is estimated that this comet will not return for another 29,500 years.
Edmund Halley, the second Astronomer Royal, observed it and predicted it would come back 75 years later. It did come back, he was no longer alive, but it was named Halley's comet at that time.
