Ela Township is a township in Lake County, Illinois, USA.

[3] Ela Township covers an area of 35.9 square miles (93.0 km2); of this, 1.5 square miles (3.9 km2) or 4.24 percent is water.

The United States Census data from the year 2000 shows Arlington Heights, primarily in Cook County, extending slightly into the southeast corner of Ela Township (covering 0.00 sq mi), as well as the southwest corner of Vernon Township (covering 0.01 sq mi) directly to the east of Ela.

[4] However, the Lake County GIS shows an even smaller extension into Vernon Township and none into Ela.
