Blenheim /ˈblɪnəm/ is a community in Chatham-Kent, Ontario, Canada.

The Chatham-Kent region was initially settled as a British colony following Alexander McKee's acquisition of land under Treaty #2 (McKee's Purchase) in 1790. Treaty #2 negotiations took place in Detroit and involved Pottowatomie, Wendat, Ojibwe, and Odtawa leaders.

Land in Harwich Township (surrounding present-day Blenheim) was first surveyed in 1791 by British settlers Lt.-Col. John Graves-Simcoe and Thomas Talbot. Early settlers built roads that aimed to connect the area with nearby Detroit.

Settlement of the area increased after the War of 1812. Blenheim was established roughly between 1825–1850. Blenheim initially sat amidst 10 miles (16 km) of dense forest. At some point, land near Blenheim was purchased by Albert Robertson. Later, Harvey Halstead, Thomas Lynch, and George Hughson were recorded as the first three lot-tenants who built homes in Blenheim.

The area where Blenheim was established was a dense Carolinian forest with wild elk, bear, wolves, and eagles. However, the region became a "patchwork quilt of farms" when the forests were cut down. Historically, the area was used to grow sugar beets, tomatoes, tobacco, and corn.

Historians Dr. Fred Landon and Alvin Armstrong state that the town got its name after resident Mungo Samson recited "The Battle of Blenheim" poem at the Samuel Brundage Inn. Blenheim had a general store by 1845. The town was incorporated in 1885. In 1837 James W. Little, a militia officer and land speculator of neighbouring Raleigh Township, purchased land at the intersection of Ridge Road and Communication Road, the latter planned by Lieutenant-Governor John Graves Simcoe to connect the town of Chatham with Lake Erie.

By 1874, Blenheim was home to dentists and carpenters. A town hall was built in 1866. Blenheim became an official town in 1885.

In 1888, a Methodist church was built. Bell introduced the telephone in 1885. Electricity came in 1888. A fire department was created in 1891. The railway arrived in 1894 and traveled through Blenheim to Windsor. The first high school was built in 1900.

Blenheim paved its first street in 1920. Blenheim grew during the Prohibition as men were involved in illegal rum-running operations. In 1924, W.G. Thompson opened a grain mill for local farmers.

Blenheim became a part of the Municipality of Chatham-Kent during the 1998 amalgamation of Kent County and its municipalities. Up until 1988, Blenheim had its own elected officials with: a mayor, two reeves, and six councillors. The current mayor of Chatham-Kent is Darrin Canniff. In the municipality of Chatham-Kent, Blenheim is a part of the South-Kent region which is represented by 3 councillors: Anthony Ceccacci, Mary Clare Latimer, and Trevor Thompson.

Blenheim received regional media attention in 2019 when councillor Trevor Thompson refused to remove an image of a toy car with the Confederate flag on it, which he had shared via social media.

B.D.H.S is home of the Blenheim Bobcats, and their colours are Black and Gold (yellow). The population of the school has declined in recent years and is currently under 500 students. The population decline is due to declining populations trend in Chatham-Kent. As well, the decline can be attributed to the loss of students from H.R.P.S, who half of which now attend Chatham-Kent Secondary School because of the Lambton-Kent District School Board's unwillingness to put a French Immersion program in the Blenheim High School, resulting in students to have to choose between staying in Blenheim or continuing to pursue French immersion.
  • B.D.H.S. offers a variety of Clubs and Athletics including: Student Union, Sears Drama, Musicals, Redfeather events, Volleyball, Basketball, Football, Cross-Country, Golf, Tennis, Curling, Rugby, Track & Field, and Badminton.
