Collin County

Collin County is an administrative district in north Texas that includes fourteen incorporated cities such as McKinney, Allen, and Princeton. The landscape extends across farmland, suburban neighborhoods, and smaller town centers with commercial strips and residential streets.

The Texas Legislature created this district on April 3, 1846, naming it after a signer of the Declaration of Independence. Settlement increased after the railroad arrived in the mid-19th century, encouraging the growth of small trading posts.

The name honors Collin McKinney, a signer of the Texas Declaration of Independence, whose legacy appears on public buildings and street signs. Residents use the wide network of parks and community centers for weekend outings, sports events, and outdoor gatherings.

The district government operates an online portal for public records, property details, and tax services available around the clock. Visitors find several government offices and service centers distributed across the larger towns.

The Heard Natural Science Museum in McKinney preserves nearly 290 acres (117 hectares) of native habitat and displays live animals in naturalistic enclosures. Visitors can walk trails that wind through woodlands and wetlands where birdwatching and environmental education meet.
