Elwyn "El" Tinklenberg (born February 26, 1950) has been an American government official and candidate for public office. He was Commissioner of the Minnesota Department of Transportation, a city council member and mayor, and a two-time candidate for the Democratic-Farmer-Labor Party nomination for U.S. Congress from Minnesota's 6th District.

Tinklenberg was born in Princeton, Minnesota and grew up on a farm in Pease, Minnesota, a small, Dutch farming community in central Minnesota. He earned his undergraduate degree at the University of Minnesota Duluth in 1973. Afterward, he enrolled at Garrett-Evangelical Theological Seminary in Evanston, Illinois. He completed his Master of Divinity at United Theological Seminary of the Twin Cities in 1977. He served as a United Methodist minister in Blaine, Minnesota, from 1977 to 1986 before being elected to the Blaine City Council and then Mayor of Blaine. He was appointed Minnesota Transportation Commissioner in 1998.

In the 1980s, Tinklenberg was elected to the Blaine City Council, and in 1987, he was elected Mayor of Blaine, serving until 1996. Tinklenberg was a crucial player in the construction of the National Sports Center in Blaine, a 600-acre (2.4 km²) multi-sport complex that includes a soccer stadium with a track, over 50 youth soccer fields, a golf course, a meeting and convention facility, and an eight-sheet ice rink, the Schwan Super Rink.

In 1991, Tinklenberg headed the North Metro Mayors Association, which worked to improve the transportation systems and business opportunities of its member communities. During that time, he gained a reputation as an expert of transportation and infrastructure issues, which led to his appointment as Transportation Commissioner by then Governor Jesse Ventura in 1998. In that role, Tinklenberg worked with Ventura to support aggressive construction and improvement of highways statewide. He worked with the Minnesota State Legislature to create bipartisan support for a regional commuter plan for the Minneapolis-St. Paul area. This plan included the construction of the METRO Blue Line (the state's first light-rail line) and the Northstar commuter rail line.

In 2002, Tinklenberg oversaw the implementation of the Mn/DOT 511 service, an integrated internet and phone system for travel information. The 511 service is used by Minnesota travelers to receive information on conditions and amenities. According to Mn/DOT, it is 10 times faster than its predecessor.

After Tinklenberg announced his plans to leave Mn/DOT in 2002, the Minneapolis Star-Tribune published an editorial praising his record and service. The editorial noted that Tinklenberg told Minnesotans "not necessarily what they wanted to hear but what they needed to hear. His frequent explanations helped lift the interwoven issues of roads, transit, housing and development to the top of the state's agenda."

Tinklenberg has been a candidate for the Minnesota's 6th congressional district twice: in 2006 he was a candidate, but was not nominated; and in 2008, he was nominated but lost the general election.

Tinklenberg was one of two DFL candidates for the sixth district seat in the U.S. House of Representatives in the 2006 election. A former United Methodist minister and manager of the Divisions of Public Services for Anoka County, he ran on a platform that supported jobs, education, transportation and as a socially conservative Democrat who opposed legalized abortion and supported a Federal Constitutional Amendment to ban gay marriage. He had been selected to receive support from the Democratic Congressional Campaign Committee and had received the early endorsement of several important labor unions.
