Not by people.
Exploratory space vehicles carrying robotic scientific instrumentation and communications equipment have surveyed Mars from orbit, and have landed and explored its surface. But there has been no "manned" (peopled) voyage to that planet.
A NASA program has been proposed that could lead to a manned landing on Mars some time after 2020; but the chances of it being adopted are considered slim, mainly because of budgetary considerations.
No, humans have not physically been to Mars before. To this day, the possibility of visiting Mars is still unlikely due the many risk and safety factors. Also, the years that it would take to get there is just too long. Our society does not possess the needed technology at this point to make that kind of trip. The cost alone just to send a probe is already millions, so imagine the money required the send a human. If this became possible, the astronauts would have to be pretty young with almost zero health factors, and have the ability to withstand the monotonous time of travel.
No astronaut has ever been to Mars.
SpaceX president Gwynne Shotwell said that SpaceX is now targeting the year 2020 for the Mars trip.
As of now, humans have not yet walked on Mars. No manned mission has been launched to Mars yet. Multiple plans and projects are in development for potential future human missions to Mars, but no specific timeline has been confirmed.
No, humans have not traveled to Mars yet. Only robotic spacecraft have been sent to explore Mars, such as the Mars rovers and orbiters. The first crewed mission to Mars is currently planned for the mid-2030s by NASA.

First we would have to actually make a successful trip to Mars...
