The Sumy trolleybus system forms part of the public transport network serving Sumy, in Sumy Oblast, Ukraine.

The owner of the trolleybus network is the Sumy city council, the passenger transportation is provided by KP SMR "Elektroavtotrans" (Sumyelektroavtotrans).

The trolleybus system in Sumy is one of the main types of public transport, covering both the central part and some remote neighborhoods.

Trolleybus traffic in Sumy was opened on August 25, 1967. The first city trolleybus was "Khimmistechko – Railway Terminal". At the opening there were 25 used MTB-82 trolleybuses from Moscow and 10 new Kyiv-4 trolleybuses.

During the period from the day of opening of trolleybus traffic through the present time the enterprise was headed by 16 directors, from them O. F. Ivanov worked the most, for a period of 11 years (1987–1998).

• 1980 — 128 (84 working).
• 1985 — 127 (88 working).
• 1990 — 145 (101 working).
• 2010 — 69 (52 working).
• 2015 — 68 (65 working).
• 2016 — 68 (60 working).
• 2017 — 68 (54 working).
• 2018 — 69 (59 working).

In the crisis of 1990 Sumy managed to preserve the Sumy trolleybus network as a whole, but since 1991 no trolleybuses have been overhauled, and repair work has been carried out only to restore the hull and chassis. Given that half of the trolleybuses have a service life of 20–28 years, the condition of electrical equipment in Sumy is a matter of serious concern.

In 2009–2010, the company carried out purposeful work to stabilize the trolleybus fleet. Along with the optimization of the production process, the company has achieved that in 2009 to early 2010 there were 46–48 trolleybuses (in 2008 this figure was 38–30) on the line daily, of which due to breakdowns in the depot returns only 5–6 instead of 10–12 against last year's figures. The rolling stock use ratio at Sumyelektroavtotrans (according to its director) is one of the best in Ukraine.

Material and technical base and reorganization of the repair service allows Sumyelektroavtotrans to independently carry out medium and major repairs of trolleybuses, including electrical equipment. Currently, Sumyelektroavtotrans has developed a system of capital and medium repairs, taking into account the replacement of electrical wiring, or its restoration, where it is economically feasible.

From 2010 to 2015, 8 cars managed to pass the CWR. There were no purchases of the new RS in 2011–2014.

In 2015, Sumyelektroavtotrans purchased 12 Bogdan T70117 trolleybuses.

On January 25, 2020, Oleksandr Perchakov, director of the organization that operates the Sumy trolleybus network, Sumyelektroavtotrans, retired. There is currently a competition for the vacant position.^[3]

On March 12, 2020, a new director, Vitaliy Odnorog, was appointed. Also in 2020, the company received a license for the right to train trolleybus drivers.

In December 2021, KP "Elektroavtotrans" received 10 new trolleybuses, those same ones who waited until October 25 and because of which the local authorities even had to "fight" with the plant. At the request of the mayor, they were registered and released on the line. This acquisition made it possible to launch a new ring route - trolleybus No. 21.

In 2016, the cost of a single trip was ₴1.25.

Following January 1, 2017, the cost of a single trip was ₴1.75.

And after April 1, 2017, the cost of a single trip was ₴2.00.

Following February 1, 2018, the fare was ₴2.50.

As of February 1, 2019, the fare is ₴4 (for schoolchildren and students ₴2).
