For people who are using web mapping libraries...

If the GeoJSON is wrapped in a FeatureCollection, as they often are when exported to a GeoJSON string by web mapping libraries (in my case, Leaflet), then all you need to do is pass the list at features to from_features() like so:

import geopandas as gpd
study_area = json.loads("""
 {"type": "FeatureCollection", "features": [{"type": "Feature", "properties": {}, "geometry": {"type": "Polygon", "coordinates": [[[36.394272, -18.626726], [36.394272, -18.558391], [36.489716, -18.558391], [36.489716, -18.626726], [36.394272, -18.626726]]]}}]}
""")
gdf = gpd.GeoDataFrame.from_features(study_area["features"])
print(gdf.head())

Output:

                                            geometry
0  POLYGON ((36.394272 -18.626726, 36.394272 -18....

Easy peasy.
