I found an article showing a picture of two somewhat similar figurines that are identified as being from Tlatilco in central Mexico in the 1500-500 BC timeframe.
Can you tell if yours has a belly-button indent? It almost looks like I'm seeing a worn one in the picture.
Other similarities I'm seeing are the way the lips and eyelids are made to stick out, the band(headband?) across the brow like in the right figurine in this picture, the wide flappy ears (like the left figurine) and the seeming lack of interest in depicting arms.
Of course what I don't know is what the counterfeit market in Mexico likes to make. With its proximity to American tourists, there has to be one.
