The Gog Magog Hills are a range of low chalk hills, extending for several miles to the southeast of Cambridge in England. The highest points are situated either side of the A1307 Babraham Road, and are marked on Ordnance Survey 1:25000 maps as "Telegraph Clump" at 75 m (246 ft), Little Trees Hill and Wandlebury Hill, both at 74 m (243 ft). The area as a whole is undefined but is roughly the elevated area lying north west of the 41 m (135 ft) col at Worsted Lodge.

Unlike the nearby hills of the Newmarket Ridge, which have steep sides but very flat tops, these hills have large drops between summits and as such have quite a distinctive appearance; Little Trees Hill looks particularly good from Huckeridge Hill near Sawston, and White Hill dominates the view from the National Cycle Route 11 section towards Great Shelford. The hills therefore have relatively high topographic prominence. Other tops include: Limepit Hill 56 m (184 ft) — Mag's Hill — Copley Hill — Meggs Hill — Fox Hill — Clarke's Hill — White Hill
