No, if the object is closer to the mirror than the focal point, the image formed is virtual.

Makeup and shaving mirrors are (slightly) concave and form an 'erect', virtual image. Retreat to the centre of curvature and the image swells up, gets distorted and then flips to a real, 'inverted' image. Put your eye very close to the bowl of a spoon and you get a virtual image but the radius of curvature is so small that it can be difficult to see it well; the image that you see is usually real because of the size of the spoon. You can tel this because you can put your finger right next to it. Have a play and prove it all.
Then look at this link.
